First indoor grow (Cookies Gelato RQS)

It looks to be a bit of light burn to me. has any of the leaves been wet when the lights on? the rest of the plant and it upper growth is looking healthy. I would not worry to much about it as its not spreading. When will you be starting your feeding of nutrients? and what kind are you using? crystal/liquid slats or dry amendments?

It very well could have been a self topped plant. or a mutation that looks the same way. Its very healthy and I would not thinking anything of it. treat it like a mainlined plant and keep it pretty looking. This will be a fun little plant to grow out. It may just have the biggest yield of them all because of this. It may also feed heavier because of it as well. assuming you are topping it the same like the rest of your plants. Good Luck and Happy Growing!

Obvious overdose of nitrogen and lock outs starting. Give her two-three full Dry/week/dry/wet/dry/wet cycles. On second you can try to add 0.5 ml/l calmag. If you feed anything now - it will stay in soil and make your problems bigger. Slow down ! Palargon is very strong, make sure you check your pH before watering !!! Some nutes need time to set up, so when you mix your feed watering give it 15 min to settle and mix before checking final pH. All the Best !

Hi cezario, I've checked your diary and it seems like only one of the plants are experiencing this. Maybe to figure out what is the problem exactly we should focus on why that plant? What could differ (apart from being a different seed cuz we can't germinate 2 plants from 1 seed) from that one to the others? What plant you water first? Guessing you have do multiple watering cans right? Are you pouring the same amount to each plant? Are they drying in the same time? Do you ever water without nutes? By your nutrient list on your diary I see you're doing 6ml/l Terra Bloom. I would agree with Roberts but 6ml/l of Terra Bloom would cover that deficiency. You're Calmag doesn't have Nitrogen?
