getting nervous

I have recently noticed that the bottom leaves started turning yellow a week ago, pretty sure i went overkill on the nutes, but i flushed it with ph'd water, like 6 or so, also been having heat issues with the 400w hps, but its getting better. The main tops fan leaves are starting to twist and shit and getting little rust spots, while the older fan leaves on the bottom have yellowed and browned and i cut em already. Im growing in ff ocean forest, using the liquid line up and monster bloom. I know notice that the yellowing is starting to fuck the younger leaves on the bottom, but the flowers are still growing, also the tips curl up when the drie out, and the top fans are starting to as well, am i fucked or is there a solution

o yea im on my fourth week of flowering

sounds like you're takin care of the right things, nute burn? possibly but you say you flushed........ good man.

In my opinion, it looks like heat stress, combined with a lil nute burn.

I used to get major leaf curl before i went with dual cool tubes, now that the temps stay below 90 i have yet to see any leaf curl.

I'm not saying this is your problem, but it looks just like mine did b4 i cured the heat being over 95 degrees.

ive seen plants get way more fucked up and still pull through

yea ive grown into a unhealthy relationship with this plant whenever it shows the slightest bad thing im freakin out,i got this 400 in a 2*2 area so the heats a lil intense

this looks like a sativa to you guys too right?

get a 300 watt hps light dude, 400 watts is too much for such a small area...........happy growin
