Tell us about your grow. pH, what type of soil, how often and what are you feeding. As much info as possible helps. To me it looks like overwater and/or feeding is the problem.
Pots are getting kinda small for them too.
So, my ph ranges from 6.1-6.4. I used canna terra professional soil. Iām feeding them every other day or 2days based on how light their pots are. I think I may have over fed them to be honest so im watering them for now. Is a flush required?
Iām ready to move them into 5gal pots, tomorrow thank you
If you could fill out the support ticket it will be helpful to the excellent growers here. They will get you back on track. Happy growing

Yeah, pots too small.
They need to be transplanted, like yesterday.
IF those plastic cups you have them in does NOT have drainageā¦roots are drowning as well as being root bound. Shouldāve been in 5 gallon buckets a week ago.
Iāve transplanted them into 5 gallon pot, i will keep posting on the development of the babies. I appreciate the words of advice. Thanks guys!!!
Iām growing autos and the strains are Blue amnesia xxl (Dinafem), blue cheese x2 (barneys farm) and caramel (Rasta boy) the seedlings are Blue mammoth also from Barneys.
I feed every 3 days or when the pot gets very light. I also follow the feed after a few days with ph down water at 6.1/6.3. Iām using all of the Canna products. The have virtually all equipment for a soil grow the only thing I feel I need is a RO system as I have hard water
this was my guess based on what i see.
Remember, they are young and donāt need much. Many times only a portion of the mfgs recommendations, and if your soil already had fertilizer in it then you are compounding the problem if you add more
If they are not overfed you may have calmag problem with the spots on leaves.
