Day 26 flower. Is this normal?

hey guys,
First grow here and wanna know if this lime green im experiencing is normal on my nitro cookies and lemon banana sherbet.
The othe 2 strains looks fine.
The pic has a bud from both plants .
Anyways,
They look super healthy other than this lime green color. The fans all praying or flat before I tuck them under each day to expose every node.
Up to 800ppm
And seeing white tips on fans indicating maybe it's an ideal nute level.
Got them in coco with mykos
Feeding twice a day DTW with runoff
Using RO water and supplementing w calimagic (3ml a gall)

600hps light 17-18inches from tops

Any ideas would be helpful. Cheers!

Another pic... maybe iron deficiency or zinc? I'm just confused bc I watch ph super closely and never let it stray outside of 5.8-6ph

It's hard to say. I'm able to get 1300 ppm during flower and with great results so your ppm might be low. Deficiency can be a bitch with coco you are either too high and causing a build up or too low both situations will give you the same look on leaves. Roots can also be your issue. A good cure all that you might want to try is a foliage spray. Works great for my friends if they ever run into problems and let's the grow continue without skipping a beat. Even though you get runoff I would still do a water flush either weekly or every other week.

hey motor, thanks for the solid advice. Gave them an epsom salt spray last night, but i think youre right. might be too low of nutes. I'm upping it to 2.0 ec this feed. Could just be one is a cal mag hoe and requires more... im definitely not running 4 different strains at the same time again.. such a pain.
As for the foliar sprays, he does that this late into flower? no ill effects on the buds?
I was considering doing a flush, but i hear in coco its not always wise to flush with water as it could disrupt the cations in the media. Run off never really shows a salt buildup either, and most of the time the ppms coming out are lower than the soup i give them. Going to up the ppms and see if that helps. I appreciate it man.
cheers

Right on sounds like you have things dialed in real nice. When I grew coco I made the mistake of using too big of pots and was killing the amount of food needed to get good runoff so I had to change and feed with no runoff then flush at the end of every week right after flush you feed them fresh nutrient with no problems. I personally don't foliar my plants but if you are running into problems and want to keep good weight you can foliar through flower until 2 weeks before harvest kills taste but does good if you like weight. Also if you want to bump up your trichomes I highly suggest trying a product called golden tree this is my current grow at day 30. Really pumps out the crystals

dam bro, this site is messing up and wont let me view the pic I'll look into that nute for sure. how are you applying it? is it a carb? what gallon pots were you in in coco when you were overdoing it? I had mine in 1 gallons then moved them up to 5 gallons the day before the 12/12 flip. They def take more water to run off for sure, and i prob poured a lot of money down the drain with nutes being as though i was water 3x a day but they seemed to grow well with it. I'd be doing that still if my ph wasnt steadily creeping every damn day. Initially i thought it was a ph problem but when it didnt clear in a week of consistant 5.8 ph, i figured it was something else. Im also under 600 watt hps so i think that dries the pots a lot quicker. yeah def gonna flush the hell outta them 2 weeks before harvest thats for sure. gonna check out that link you have on making hash... something tells me im gonna need that pretty soon

Every grow and situation/environment will be different. I've also got a sherbet strain in flower as well (week 6). It's Purple Sherbet from in-house genetics. For me personally, I RARELY go over 700ppm on the .5 scale or 1.4 ec. In 100% coco, 3gal fabric pots. I never use cal mag and I never foliar feed. If those plants were in my grow area and looked like that I would feed them less. I water once every 24 in flower and every 2-3 days in veg. I use powder nutes. I use potassium sulfate as a booster for a couple weeks in flower and I feed till the end and keep 'em green. If I want them to fade I back off on the N the last couple weeks. All this is just my experience with my grow space and conditions.

Cheers and happy growing everyone.

hey arkitecht, thanks for your reply. my real problem here is out of 4 strains, ive got 2 looking like champs, and two with olive color darker leaves. Only this 1 strain ( lemon banana sherbet) has slight yellowing at the tops. No cal mag in 100% coco? are your nutes specifically designed for coco? Are you using RO water? I cant see how you could get away with no calmag in coco... mine are calmag hoes. I was feeding them at nearly 7 ml per gal and they loved it... when i dialed it back down to 3 ml per gal i started to see the yellowing on the sherbet. Again, you nailed it... everyones environment/situation is different.

arkitecht one thing last bit.. when i was feeding 3 x a day, my nutes were cut way back to around 700 ppm on the .500 scale. Once I started watching PH closer, I dropped feeding to once a day, and started bumping up the ppms. I noticed the yellowing a little bit BEFORE the nute increase. my lower leaves all look great too, which tells me no mobile deficiencies ( that I can tell). hadnt done a foliar spray before up until two nights ago with the epsom salt. I dont see any difference so i might hit them one last time and call it quits.
the one thing i royally messed up on was the nute regiment the week i switched to 12/12. I stopped feeding them veg A+B and just went right to flower. I know this should be done slowly, with the 2nd week being a mix and the 3rd week going into flower nutes... my plants didnt seem to mind, but now that im on week 4 im starting to think that mightve been the culprit. oh well, live and learn.

Nope. Not a coco specific nute. Jacks hydroponic from JR. Peters. Lots of peeps on here use it. Used the citrus feED as well by them. And I let my pH swing in the range of 5.8 - 6.2. I also feed them the same balance of NPK from seed till harvest. If I want a fade I'll back off the N at the end,. But for me personally, I've gotten better harvests this way with better quality smoke. And not sure why but Cal mag has always caused more probs for me than it's helped. So I've not used it In years. I change the NPK ratio depending on what the plants say they need. As far as H2O goes. Luckily here in Portland, the water is 12ppm out the tap so I don't use RO. I do let my rez's sit full undisturbed for 24 hr before I add nutes.

Cheers.

DAMNN! 12 ppm? thats insane. That explains the great beer you guys make. I used to let my ph swing a bit too, but the guys at my hydro store looked at me like i had 3 heads when i said that. The most frustrating thing about growing is not just differences of opinion, but EXTREME differences. one person swearing by this method, another warning that same method could kill your crop! its almost comedic. I'm running low on my nutes, i might have to make the switch to that line if it means not dealing with cal mag. How big is your nute rez and how quickly is your ph creeping up? my current setup makes it damn near impossible to clean out the rez once the trellis is on... my one fatal flaw. I think me not cleaning out the rez is causing bad bacteria and other junk to build up and making my ph rise quickly.

My rez's are 50 gal. I bleach them every 2 weeks. My Ph stays stable with jacks. I dont Scrog since I like to be able to move my plants around and really get in there, too hard with a net. I don't flush ever either. Everyone is going to have an opinion. Learn what you can leave all the rest. I've found simple is better and that all this stuff everyone tells you to use/include in your nute program is bullshit and expensive. From my experience NPK is NPK no matter the brand. So I go with what's inexpensive and gets great results the only thing I add is sulfer (potassium sulfate) during mid bloom and just for two weeks. Jacks costs $180 including shipping and the potassium sulfate. That's like 50lbs and lasts me 3 years or so. Can't beat that. Best I've found.

Cheers bro.
