Not light stress, but the beginning of magnesium deficiency. Giving cal/mag will solve this and prevent it from getting too much worse.

3rd week since 12/12 and chlorosis is getting worse !!! Will my crop be crappy ?
Brought EC to 1.6, added 21ml of calmag, had to add 2L of osmosis water because the EC was 1.78. I changed the bad Ph probe and I let it fluctuate between 5.75 and 6. Should I remove the aluminium foil on the pot to let them breathe ? Not sure they are overwatered, I'm desperate

Breaking light cycle during flowering
Does breaking the dark cycle after half an hour of dark will stress the plant? I just opened the box 30 minutes after the light went down during the first week of flowering. Can this make my plants hermaphrodite?

Warum werden die Blätter auf einmal so schnell gelb und welk?
Hey, meine Hawaiian Runtz ist Ende 4. blütewoche. Gießen tue ich alle 4-5 Tage mit 2-2,5 Liter Wasser und 6,5 ph Wert, immer ziemlich identisch mit Terra aquatics ph Tropfen, also sollten ph Fehler ausgeschlossen sein. Temps am Tag ~28 und nachts 26 grad Celsius. What’s wrong?

Deficiency?
My current grow is on its 5th week of flower and many lower leaves on each plant have begun to yellow then develop brown spots. I’ve did a little bit of research and I think it could be a nitrogen deficiency. Any help is appreciated.

Pin the tail on the deficiency
Some yellowing that developed on Gelato Auto in the last coupla days....my guess is nitrogen deficiency since feeding has been light throughout growth but I'm still new to the game and would love to hear from some more seasoned growers

Why is One growing perfect the other is struggling
Why is one of them doing so well growing better deep green leaves and the other is at least 2 inch shorter and leaves are yellowish. I’ve been feeding them both the same I’ve missed the shoter one of the soil is still damp. I’m guessing nutrient over load so thinking do a flush

When should I switch on the other half of my LED light setup?
Hi guys, I grow 6 plants in hydroponics in a 4x4 grow box and they are 2-3 weeks old (about 7-8 cm tall). I use MarsHydro TS 3000 LED (450W) which have 2 seperate LED panels. Right now I run only one panel and would like to know when I should turn on the other panel. THX
