To fix it, go to quarter strength and the extra run off should start rinsing the excess nitrogen out of potter.

Both, Water less but more frequently, next time mix for perlite into the medium so it won't have this issue. and feed less N in the irrigations. Good Luck!

Surplus or deficiency?
Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

What is she telling me?
Anyone know what she’s going through? Four weeks old, using tap water with hydroguard and GH FloraTrio nutrients. PH seems to go up from around 5.6 to 6.1 in a matter of hours. Ppm=635 EC=1.2 right now. Been going very easy on nutes, about half strength still. Could that be it?

Day 20 Flower. Leaves curling
Leaves curled over 12 hour light cycle. Ph 6.0. Ppm 950. I have been battling ph drop for a week. Lowered Ppm to 900 from 1100. Seems to have stabilized the ph and now the leaves are doing this. I’m looking to do the day 21 strip of most leaves tomorrow. Should I be concerned?

Looks like light stress I assume with the canoe and curl. Moved light from 100% to 75% Stil at 35in from canopy. Should that do the trick? Also should I have already had it at 75% and moved it to 100% during flower? Or how do you guys do your light power

The leaves are curled up, it's hot in the room these days, I guess this is the reason. Plants growing fast anyway, humidity between 48%57% but I'm worried because of this leaves problem. Should I ? I do my best to cool down but can I do something else ? Mist the leaves ? Thanks !

Hi guys, I’ve noticed the leaves of 2 plants are curl upwards. I think overwatered, Day 9 I’ve watered two times (wrong) and after checking Day 8 too. At day 10 I've didnt watered, and today I've seen the soil dry, so I putted 100ml water. What do you think is causing this curl?

Any ideas on my lower leaves cupping? I'm thinking a root issue from overwatering. I last watered 6/11 and this started showing on 6/13 and has progressed. Soil is still moist and fungus gnats popped out of nowhere this week as well. Have SNS 203 for next watering
