Pics of some issues with my babies

I will try to be brief.
Started these from seed and put in FFOF in 6" pots under T8 lights. Water PH is steady 7.0 with plenty of air movement in the walk in closet with door kept open.....and endless trips in and out to breathe on them and admire what the will grow up to be. Everything was going great for 3 weeks until a few days ago. Most are 'droopy'/leaves limp with bottom leaves turning yellowish. I am attaching pics. Please, if ur just gonna post some crazy sht to get ur posting count up, just save it. It would be kool to get some real opinions/facts/help with my 'issue/s'. Pics aren't the best from phone, but should be clear enough to get the jist. I have not been soaking them and haven't used any nutes or done anything different than wat I've done for 3 weeks.

Peace and thx in advance,

its mobile deficiency, either P or K, i really cant tell, just feed them more

forgot to mention ur pH is fucked up. should be 6.5

Looks to me like zinc deficiency, but I don't think that's very likely in FFOF, lately we've been hearing/ seeing a lot of stories with complaints of seeds/ seedlings burning because it was hot.
As far as the droop, your soil DOES look kinda dry.
How are your watering habits?
As your rootball grows, it will drink faster I think.
I agree with above though, try and get your PH down a little, but remember it will drop a little when you add nutes.
You may also be getting close to rootbound in the larger one.View attachment 2452711

Rx: flush and balance to proper ph. light dose nutes and wait.

Personally I don't think T8 lamps are sufficient for growing, if you must stay with florescents you're better off with T5 HO, better yet MH and or HPS.

Flush out the soil... then do a LIGHT feeding with some nutes, pH to 6.5... not 7

not zinc. zinc is immobile, immobile deficiency with the exception of molybedium starts from the top of the plant working downwards.

I haven't used any nutes and the water is from a pur brand filter that I put in a gal sprayer with a mosquito dunk floating around to keep those POS gnats from makin root destroying babies in the soil! I have only measured the water ph, not any run off...and not those soil ph reading prongs that I have yet to hear anyone having good success with. Isn't soil known to be a buffer anyway? They were doing great until a few days ago, and it was like bam! I will flush one and get a ph reading, but I'm fairly sure it will be 'ok' due to ffof having a rep of being 'hot'.

For my T8 lights, those are just to get my babies to the 30 day mark upstairs until they are considered 'mature'...then downstairs in a 6.5x6.5x6.5 FT grow tent with filter and 1000 watt mh ( slowly introduced to the new light for a few days) for the remainder of the veg, then putting in a 1000 watt hps bulb. This is how I did my first grow earlier this year and it worked well. Could it be that the plants are 'done' with the 6" pots as well as the soil they are in, and 'ready' (or close to) to move into a 3.3 gallon pot with fresh new ffof? I have on standby, the Fox farms trio bottles of nutes to use....was going to wait until 3-4 weeks after putting them in their 3.3 gal with new ffof, to use. The yellow/ish leaves starting from the bottom was/is a concern, and I was leaning towards it being N deficiency, but that in combo with them going 'limp', got me pretty freaked.

I appreciate all the replies so far ppl.

if its n, the leaves would be yellowing gradually. urs look like phosphorous. cant hurt to try.. if u over fert with N u are fucked. if u give them a little extra phosphorous, it wont hurt

i can hear them screaming...................FEED ME

Any one thing that stands out as a good phosphorous supplement? I'll flush one later today and get a run off ph reading just to see. Also I have one plant that it only a week and a half old, that shows no signs of any issues.....same as these did, until the other day. Just a note, these are all from the same strain (Super Skunk from Nirvana seed co) I had from my first grow. I took a male and female out of the bunch, put them in the other tent together, alone, and let them do their 'thing' for a little seed stock. I failed big time with a clone project, but should have better luck this time around.....if and when these make it to about a week into flower.

Trust me, my first thing I wanted to do is break out the grow nutes and give my babies a dose.....but if there is a lockout, I would just dig a deeper hole.

any bloom nutrient should have phosphorous. you should breed imo, unless u know what ur doing. only breed if u want to isolate phenotypes out of a strain. if u want to clone properly, build a diy aeroponics cloner.

measure the runoff water, should be more accurate pertaining to your growing medium.

The plant looks locked up..... This is due to a PH of 7.0, I've always PH'd 6.0 in soil and produced good healthy plants, as above flush the soil out and start again..... Add small amount of nutes, EC the feed and start at 1.0 -1.2 and see how the plant reacts to this, if all is good then a week later up your EC to 1.4 and so on until you've reached recommended maximum nute. Hope this helps

pretty sure soil is 6.5

Yea, I'll know more after reading the run off ph. Pretty sure adding 7ph room temp water to this soil, will buffer a lower ph....but only one way to find out.

5.8-6.5 .... Just my preference and as stated above I've had good results with.... Not disagreeing with your 6.5 though )))

nope, 5.8 is hydro. 5.8 to 6.5 may seem like a small number to you. but in chemistry it is actually a couple thousand extra hydrogen ions than you really need. exactly why hydro has its own pH, soil has its own pH. plants dont absorb nutrients as well in just a couple of tenth of a points of pH

Need to check your stuff..... Not sure if it different in USA but just checked and its 5.8 to 6.2 in uk ..... 6.5 = probs
