Possible K deficiency [PICS]

[in.music.u.trust]

Our plants are about two months old and were stunted for the first month due to lack of good lighting. We remedied this by getting a 400w HPS. Currently, we do not have a fan. First, the leaves got very droopy and then started turning yellow on the lower branches starting at the outsides of the leaves. The viens turned last, not fading until almost all the color was drained out of the surrounding leaf. There are also some brown spots that almost look like small cigarette burn. Some of the newer brances at the very bottom of the plant are growing in yellow. Ph is around 7.3. We are using Fox farm soil and fox farm grow big fert.

Heat stress is part of it. Get an exhaust hooked up ASAP and if that hood can be air-cooled, hook it up directly to the hood.

Crap. We live in apartments and can't cut holes or anything in the walls. Is there any alternative solution, like keeping those doors cracked while the lamp is on, etc.? Also, once we find a way to fix the problem, about how long do you think the plants will take to recover?

You could always go get a door and replace it with the one there now. You can cut holes in that door for ventillation because its yours. Then when you move throw the old door back up....:wtf:

Just remeber to use enough ducting to connect when the door is opened all the way. Also place the exhaust at the top of door. Simple solution..Invest in the exhaust this can make or break your grow..right now its breaking it.
