Just wondering what is going on with these 2 plants. The problem is similar on both. Did I overnute them or is it a pest problem. One is a 4 week old sensi star clone and the other is unknown bagseed. I am using ocean forest potting soil, dosed them with grow big and big bloom. Never noticed any problems until i used the big bloom, thought that was totally organic and wouldn't damage anything. Currently using a 200 watt CFL. I appreciate any help on this matter.
Seems like Nute Burn to me

Looks like possible overnute and/or overwatering. Use measuring spoons, don't approximate. They have a dosing schedule. just click on < soil - english >
I use this schedule for my crops, except I cut the dosage in half, and feed twice weekly. (and I only give a half dose per week of Big Bloom)
Works great.
Looks like nute burn here to me too. Had one looking like this the other day, flushed the soil, new growth looks better.
Thanks guys, do you think i should flush them?
If getting rootbound (are they in 1 gallon pots? Hard to tell.) you could transplant to a larger pot, and water with plain, ph'd water for the first week.
Otherwise, a minor flush, and nutrient adjustments for future waterings should be fine. :thumbsup:
Rusty, as a matter of fact they are in one gallon pots. Was gonna wait another week and transplant them into bigger maybe 5 gallon. I want to flip them next week when i get my dr120. Would have to redo my veg light if i transplant them right now, what do you think? If I need to, i'll get it done. Thanks for all your help. I have some 3 gallon and 5 gallon.
Just because something is organic (or 'organic-based' like FF) does not mean it can't burn.
You're running the full FF suite? Gotta follow the instructions posted on their site, but always start off WEAKER than recommended.
Classic burn. Flsuh well, feed at 1/2 strength of whatever the bottle says to use for your life stage, and allow to dry better between waterings.
Any slowing of damage to the leaves, yet? Are the new shoots a bright green?
I think I'd wait to transplant them. At least for a few days. Likely they are a bit stressed, and transplanting won't help much right now. I'd give 'em a bit of time, so you can observe how they look after the flush, and go from there.
I usually take baby-steps. From one cup, to a one gallon, to a 3 gallon.This takes me thru veg. Then, I transplant to a 5 or 7 gallon pot, a couple of weeks into flower.
Doesnt look like its getting any worse. Will wait to transplant a few days? How long do you usually veg? Day 31 here, by the way, this is my first attempt to grow. New growth is bright green and healthy looking.
