Okay I would love to get some advice from a more experienced grower than myself. I'm growing three plants, however only one of them is showing issues. It is a GHS Super Lemon Haze and it is mid way through Week 5 of flowering. Fox Farm Nute Trio Feeding Schedule, and Fox Farms Ocean forest soil. I've been using 1 tablespoon of Blackstrap mollases per gallon every other watering. My water is RO water always PH'd to 6.5-7.0. I water when my moisture meter reads as 0.0 or 2.0 out of a scale of 10.

he Schedule looks like this.
Day 1: Water With 1/2 Strength Fox Farms Nutes
Day 2: No Water
Day 3: Water With 1Tablespoon Molasses per Gallon.
Day 4: No Water
Day 5: No Water
Day 6: Water With 1/2 Strength Fox Farms Nutes
Day 7: NO Water
Day 8: Water W/ Molasses

Lighting: 2x 600 Watt HPS for 3 plants, 5 Gallon buckets, RH is 40% at night, 50% during the day Temp is 70 During night and 80 during the day. It is growing in a closet which I keep the door open with a fan blowing air into the room, and a fan in the room circulating air on a low setting.

I just flushed her tonight with 2 gallons of R/O water at 6.7 PH. I measured the PPM run off at 678PPM and 6.8 PH. Is it nute burn? Cal mag def? Cal mag abundance? Rust fungus? I'm really hoping I can save her I'm really looking forward to the smoke. I can post more pics tomorrow if needed. Any help will be greatly appreciated. My other plants are showing yellowing leaves that eventually turn brown and died off and I figured thats normal in flowering, none of them have weird spots like this though, and the twisted leaves are crunchy. I'm really worried about the brown spots.

Is that a sativa? It looks really dark green for one. Also, it looks like a potassium deficiency. Though that's just speaking from pictures, not personal experience.

Well I have a SLH that grew great and tolerated nutes and then around the 5th to 6th weel of flower she started to yellow really really bad and now nothing is growing, and she just looks not very good...the whole plant is basically yellow...I need to do some serious detective work on mine...she might be rootbound...she might be overfed...but I have skipped numerous feedings since she started looking poorly...then I though perhaps a nitrogen deficiency so I gave ehr some nitrogen and a small amount of color returned to the leaves...but not enough for me..it looks like nute burn to me...just like mine, but I am not so sure nute burn is the issue...

Yes it was labeled as a "mostly sativa" strain according to seedfinder. I've been feeding it the Fox Farms Trio Tiger Bloom since the first week of flowering, maybe it doesn't contain enough potassium. Thanks for the advice I'll take it into consideration, I'm just afraid I'll burn her worse if that is the issue.

Did you get dark brown spots around the edges as well or just the entire plant turning yellow? And yeah she was growing perfectly up until this problem started less than 7 days ago around 5th week of flowering. Hopefully we both fix these issues.

Thanks hopefully I can figure it out before its too late.

they will be fine just have faith you can fix it. it sounds like things should be getting better, but yeah better pray ti the weed gods lol.

well im happy to report that my babies are looking much better since the flush. i still havent added the calcium vit yet. after changing the water last night and leaving them in plain ph adjusted tap water that sat at all night with a bubbler in it, they seem to be on th move again. they were much more perky and there was noticable new growth at all new internodes, and its grown almost an inch over night. i think some of the fan leaves are still kind of shrivling a little bit, but i think thats the nute burn finishing its course. i think ill wait till the growing has slowed before adding half str nutes. hopefully the res change after the half str nutes will be when i add my bloom nutes

thanks for all the help. im starting to learn that the growing takes patience i was lacking...but again, thanks for all the help my dude.

How old is the soil? Is it fresh? What ppms are you running at? I've found ffof to have a medium level of food and it really starts to break down a little later in the grow if not cooked. Usually a little tougher to have nute burn with organics IMO. When was the last time you fed her?

Well the run off tonight was a 670PPM. When I feed her nutes the PPM is 700. The soil is about 3 months old from a fresh bag I purchased at my hydro shop. I fed her nutes about 3 or 4 days ago at 1/2 strength 1sp of Tiger Bloom 1 tsp of Big Bloom and 1 tsp of Grow Big. What do you mean by not cooked?

polyarcturus · Apr 6, 2012

what yours temps? it loks like its to hot. a K def would look similar, where did the yellowing start? start and why did you let it go for so long without asking for help?

jsamuel24 · Apr 6, 2012

Some of my bottom fan leaves have started to do this.

Not many of them and mostly the older older growth. if I leave them on where the yellow is slowly turns to black as the leaf yellows out then it becomes brittle. Is it something I should worry about. Rest of the cannopy looks like this.

Thanks in advance

polyarcturus · Apr 6, 2012

thats normal with scrog and lower growth that does not get enough light, it has to do with N not being able to be photosynthesized

iwas looking at your canopy thet yellowing color at the center of the leaves is lack of N, i would up the dose a little, what your nutrient system? and media?

Thanks poly, with everything looking good on top i really start to worry when i see anything different, know what i mean?

polyarcturus · Apr 6, 2012

hey thats cool i wait sometimes i could just be really fresh active growth, that always appears yellow. thats why i was asking about your nutrient system and media. but its all good.

Sorry Poly, just saw your second post. I am using Earth Juice Sea Blast Transition right now. it is 8-32-14. I had added a teaspoon and a half of Fox Farms Big grow with the feeding today (about 10am this morning in dark cycle) since its still week one of flowering. Wanted to add some extra N. Media is VermiSoil from Vermi-Organics.

polyarcturus · Apr 6, 2012

sounds fine. good call woth the N, hell dont stop N till about halfway or more thru flower. im organic with all my N so i add it all the way thru to the end. i will say tho during the first week 12/12 a high dose of P will get things started but its better to back off afterwards

Was planing on using the transition for the first week and a half of flower, then switch to the bloom. Think thats too long of transition?

polyarcturus · Apr 6, 2012

no i dont think so i use transition nutes the whole way basically.

Temps are 70 at night and 80 during the day. Maybe she is too close to the light? But then wouldn't the top be more burnt? She is about 5 inches from the 600W HPS but its in the cool tube and it doesn't feel hot under my hand. The yellowing started in the upper portion of the plant. At first I didn't ask for help because I thought it was a mag/cal issue so I started adding the blackstrap molasses. When that didn't help I posted here.

polyarcturus · Apr 6, 2012

im thinking over nutrient, and pull it back form the light 5 in is too close when a plant starts looking bad. may feel alright to you but HPS puts off IR which can make the surface of the leaves very hot.

where did the yellowing start at? this got this bad over the course of 7 days?

bigboybuds · Apr 6, 2012

Hey poly, been reading through this thread and thought you might be able to help.

A little background- This is day 5 of my new grow. I transplanted these clones out of veg to new pots. Using soil. Its kind of my own mixture.. Some Connoisseur soil (made by Fafard) used it my last grow, with no problems.. I mixed in a bag of cheap potting soil, and a bag of sheep manure. I think the npk of the manure was .05/.05/.05 . So nothing huge.

I am vegging under a 600watt MH, light is about 24in from the canopy. Running 18/6 atm.
Using AN M/G/B 3/2/1 for veg, about half strength. Did a soil PH test its last night (dont have meter) with a test kit, and it measured nutural.

Noticed this starting yesterday, and it got worse over night. These pics were taken about 10 mins ago. What do you think?

I pulled the light so it is about 11" away now. The yellowing started on the middle upper half of the plant. On the leaves itself started by the leaves turning yellow. I thought that was normal in flowering, but then those brown spots started appearing and spreading and soon the leaves twisted. So yeah that happened slowly over the course of 6-7 days. Should I just step back and let her sit? I already ran 2 gallons of RO 6.7 PH water through her last night.
