Hey all,

Frequent reader, haven’t posted....well maybe ever come to think of it, but I have had an account to view photos for some time. I’ve looked into my issues extensively and am have a few thoughts in mind. So that you better understand my setup, here you go.

One bag seed plant grown in 5gal fabric pot using a mixture of approx. 25% perlite, 15-20% sphagnum moss, 15-20% black compost, MG either raised bed or potting mix and some cactus and citrus mix to help with drainage.

I was thinking nutrient burn because that compost could be hot, in addition to MG soul, I think it could be a lot for the plant. My PH has been steady around 6.5 in and out, maybe a bit on the low side at times but always in range(probably from the moss). I’m in a 2x4 tent, with 300ish true led watts about 20” from canopy and an exhaust fan(no intake). Temps rarely get above 80, or below 70, but relative humidity has been between 50 and 80 the entire grow...it should be going down soon. I move her into the yard on nice days and she’s adjusted to the sunlight. I’m just over 6 weeks from seed, and this problem appeared about a week, maybe 9 days ago. I gave her a “mini flush” of ph’d and distilled water without any nutes(haven’t fed her anything so far at all)but only watered 7.5 gallons for my (although sold as a 5gallon),what I think is a 4 gallon pot. I wasn’t able to check on her for a few days and came back to quite a drastic change. Lots of yellowed lower and teenage fan leaves...up until now, new growth has been unaffected but I see two tiny “splotches”. Maybe a little stunting but like I say, overall until now, she’s been a happy plant. Fimmed, topped, supercropped and lst’d. I’d hate to lose the effort that went into her!

Ohh splotches leads me to think “P” deficiency? But the drastic yellowing makes me think “N”. I’m also thinking mobile nite because it did see to hit old fan leaves on the bottom first...they scrunch up and die then it moves up to younger stuff. Could be root rot if the root zone got hot in the sun outside?.....just spitballing here.

It’s a toughie, because PH is running fine, and she’s been happy. I’m working on reducing RH in the meantime.

I would appreciate any input!

And thanks for welcoming me to your community!

P.s. looking at the pictures I noticed that some leaves look deformed or eaten when in reality those are leaves where I had fimmed...correctly or incorrectly lol

starving to death !!! give her some veg food now. the "flush" is what made it that bad. she was low on N when you flushed , now she is starving to death.

go ahead an grab some FF grow big and big bloom to go with your tiger. use it full strength 2 or 3 times in a row. then go down to about 7ml per gallon of grow 1-10 ml of big bloom per gallon.

Hey fellas...I have been following your guidelines and the issues I had before seemed to settle down...

I don’t think I’ve overdone it on nutes although it’s possible.(I’d prefer to be a little light than have to flush etc) but am seeing some changes.

I just switched her to 12/12 and beforehand, gave her 24 hrs of dark...some people say it speeds up the actual flowering of the plant, who knows but I gave it a shot. She gave me some expected stretch and her new growth is now super lime green. Is this normal? Only my second grow. Could this be an over abundance of something, or just the light color of vigorous new growth?
