Leaves fading and dying, started from bottom but spreading
I’m starting to be at a loss with this. Calmag issues earlier in veg, seemed to improve for a while but now bottom leaves started to die - I thought this was just due to beginning of flower but it’s getting worse and spreading even to healthier new growth. PH (should be) fine.

Shock or Genetics?
On day 3 or 4 of this plants grow a small item dropped on her and damaged the stem. Do you think that early shock is the cause of this overall reaction or should I be blaming genetics?

What's Happening to my Glookies? Lower Growth Yellowing with Grey/Light Brown Spots.
Yellowing with grey/light brown spots occurring on the Glookies plants (starting from the tip of the leaf). I believe it may be due to the Fox Farm Ocean Forest soil mix but any advice or input on what is possibly happening is greatly appreciated. Fingers also fused together.

Sick plant, could be temp, nutes, too much water?
Leaf tips looking burnt and wilting in flower ... keeps getting worse no matter what. pH 6.8. Raised light. Too many nutes? but a couple days with water only and it's still getting worse. The other plant seems fine. The buds seem OK. Maybe heat? Soil is 69F. Overwater?

Overwatered cubes in hydro? Too close to the sun? or effect of having add
Hi All, I have issues with my first hydro grow - i effed up. I think i was too slow in the transfer over in the tank. Light is 200 PPFD, EC at 0.6, and barely added any nutes. Did i manage to overwater some of these plants by having them too close to the net pot?
