One looks like a iron deficiency well the other looks like a magnesium deficiency. I'd definitely think about transplanting them into a larger pot. Give them a well rounded feed and they should bounce back quickly. Remember to use micro and cal/mag

Have popped 2 seeds, 1st week of grow. One plant started to roll down her leaves extremely right after losing the shell. Anyone knows why? What to do? Had extreme dry RH in first days, it dropped down to 36% sometimes. Both plants have root fungus in substrate. Thanks!

Burning Edges/Yellowing and Drooping?The yellowing has gotten worse and I'm noticing slightly burnt tips/edges and some droop. Could this be burn/deficiency or over/underwatering? A combination? Is there anything I can do to fix this early or is it just a matter of giving them some time and less nutrients? Thanks!

Droopy plants Lately my plant's have been droopy. The leaves were going up until I used early nute mix - BioHeaven, Activera and RootJuice from Biobizz - their NPK is low so I didn't expect them to affect plants. Since then I've watered with clean 6.5 water when dry, so its not overwatering :/

Reason for red / lilac stems of fan leaves?The stems oft many of the fan leaves turned lilac over night. Not only the top ones, so I don't think it's stress from the light. Could some light defoliation the two days before be the reason? The only other thing I changed were 5ml of bio Hesi bloom nutrients. Otherwise healthy

Help. Leaves on young plant curling downwards The last few days I've noticed the leaves wilting, I let the soil dry out abit at first because I thought I had given too much water but then last night I watered it with ph 6.3 run off 5.0-5.5 and the leaves still haven't sprung up. Is there something I've done or can do to fix?

Tip of leaves burnt Has been vegetating for a while and growing nice, only noticed these around a week ago and dont seem to be going away. It looks like a nutrient burn? Been feeding it pH perfect Bloom, Grow and Micro 3 times a week (4ml a litre), so didn't think it would be a deficiency. Thanks!!

Leaves pointing down Hi guys, this plant is a photoperiod and it 's 1 and a half weeks into flower. As you can see from the top the plant looks fine but the bottom 1/3 of the leaves point down and eventually fall off later idk why. The plant is still growing and flowering but i'm a little worried.

Nutrient Excess Can someone tell what nutrient is causing the burn on the leaves ? The plant is light green so probably not nitrogen... how would you feed it with biobizz ?
