Plants are looking sickly, not sure what to do.

[easn]

I'm a little concerned about my plants as their coloring seems to indicate a potential deficiency. That being said, I had to flush the shit out of my hot FFOF soil due to nitrogen toxicity 1 week and 4 days ago. Up until that point I have only fed my girls water. Since then though I have watered twice. I use the knuckle method and feel down an inch or 3 and check for dryness, lift the fabric pots to check for lightness, and look for drooping leaves.

The first watering with plain dechlorinated tap water, I checked my runoff. The PPM read 1191, where the water was 587 just after adjusting the PH to 6.5.

The second watering with dechlorinated tap water I didn't measure the PPM. The PH was adjusted to 6.5 before and after adding the General Hydroponics FloraSeries nutrients at 1/4 strength (see attached feeding schedule #3).

Overall the older leaves look okay, they still show some residual effects from the nitrogen burn (clawing, cupping, yellowing, etc), but I do feel the new leaves presenting as lime green, inconsistent coloring, as well as the cupping, indicates a problem.

Because of height constraints (4x4x80" tent), I need to flip these girls to flowering very soon. I feel like they are already too tall and most are at or above 18". This is my very first grow and wanted to do 100% natural as in no topping or LST. I just wanted to study and learn what the plant does growing naturally. But I will do some topping or LST or whatever to keep things moving in the right direction.

So I guess my questions are:
Is there indeed a nutrient deficiency?
How do I correct it if so?
Can I flip to flower (12/12 lighting) in their current state?

Thanks in advance.

5-gallon fabric pots, straight FFOF soil. 600w MH light, 4x4x7 tent, 24/0 light schedule. All Indicas or Indica dominate strain

I don;'t know your nuts but the 1st month of using ffof you should only water. nothing else. enough nuts in ffof for sure. week 5 I start nuts.

I only added 1/4 of the nutes after I flushed the crap out of the pots. And by flush I mean flush, I ran probably 10 gallons of water through each pot to wash the nitrogen away. I was instructed to water once after the flush then introduce nutes gradually in the waterings after that. The leaf coloring was happening before I watered Friday with the nutrients.

Flora nutes suck, so does ocean forest. Hows your air intake aswell

Right now I just leave the front tent door partially open, the two vents towards the bottom are open as well. There are two 8" oscillating fans moving air in the tent. Do you think I may have stagnant air? Also, I'm kinda stuck with the FFOF, what do you recommend for nutes?

I love Ionic or Soul Synthetics and Promix. Seen alot of people have problems with ffof and seen bugs come from the soil. Just my experience though.

Foliar with just fresh water and flush till they recover, but don't over water soil

Light burn 100% if u see yellowing just at the tips of the leafs closest to your lamp there's your problem...I don't know all your problems but I def recognize some light burn because I've done it..

Could be but he does have a little space. I've had em pretty close but was using co2. To me the dark green and burnt tips looks like excess nitrogen, hot soil. They don't look bad though imo the nitrogen and salt buildup could linger and taste in the final product if not flushed.

they dont look too bad. just a imbalance of nutes. not dark green to the point of leaf death. could try different fertilizer.
my trick is doing a hard reset. give a good flush with water and a final flush with some peroxide added so the roots wont rot.

Keep LST into the first 1-2 weeks of flower but don't top them any more at this point. Top 1-2 times early then LST/trellis

So by flush you mean just water as I normally would with plain water? I usually use 1 gallon per pot.

Im using a 600W MH light at 14" from the canopy top

Yes. also remember they stretch in flower alot more too

That's my concern. I wanted to flip to flower by now but I'm afraid with having these issues that it's not a good time to flip. They freaking grow taller by the day...Can I flip now or should I wait till things resolve?

FFHF 80% perlite 20% and this...

 

[Old_fart_stoner]

OOPS...forgot to mention no nutes for 30 days in final pot.

These plants have good definition and will be fine if you start slow adding nuts. Don't blame or get ride of ffof. Its perfectly fine and grows super plants if you don't add anything the 1st month using it. The plant nerds hate it and chase the ultra organic many items package that's great for experienced. The overflushing of water will delay them looking good for a few days but will be fine. The distance for that light is fine for healthy happy plants. Anytime stressed give them 6-12 inches extra room for a few days and then closer. Go light on your nuts at 1st and forget package recommendations that are way too hot for newbies. try maybe 25% recommended but others can suggest who use it. The perfect newbie nuts i'd suggest seabird guano a tablespoon every 2 or 3 waterings directly to soil. I use it all the time. nice looking plants actually just stressed at the moment.

Okay that makes me feel much better. Thanks.
So could I just switch to the seabird guano and ditch the General Hydroponics (again I have only used 25% in a single watering)?
And with the seabird guano, add a single tablespoon to each pot every 2 to 3 watering. And do this schedule through flower?

Also, can you suggest when to start flowering? I'm already running out of vertical space with the aircooled light.
