Light burnt? rapid yellowing in early flowering?

cxb3590 * 6 (36v @ 700ma 10" canopy height)

Flowering stage (forgot, but both have been almost 60days since germination) when i compare to other plants flowering stages, mine look like flowering stage 3 for now? however i don see any trichomes developing yet.



Strains:

Left: Lowryder Auto Right: White Widow Auto

Growing medium: Soil + fabric pot



Room Temp: 82f

Room Humidity: 57%

i have questions:

are they suffering from light burn? and too fast N deficiency towards flowering?

Looks like classic nutrient deficiency to me. Up your feed just a bit, and contrary to popular opinion, make sure it has some nitrogen in it.

Nice . Turn it up. Nuke um . The dif varieties will want a little something dif. See if you find other treads with your individual stains and treat each one as if was the only one .good luck and damn your going to have a jungle lol.

I was kidding about nuking em

That's why I love dyna grow bloom nutrients, they contain 3% nitrogen to provide some but not too much in flower.

theres signs of overfeeding, tips don't get burnt because you aren't feeding enough. looks like Mag deficiency. what are you ph'ing at? Mag needs at least 6.2 to be absorbed.

I reckon the grower has been overwatering them. Not letting the plants dry out properly too. Imo you have caused the lockout by overwatering and a bit too much feed.

I would let them dry out so much that they as dry as a nuns pussy, back the lights off a bit if you want, but mainly to suit the environment. Feed them ph 6'5 water, but not lots, just a bit each day. Make sure the plants ain't getting too cold. They'll soon bounce back.

Please anybody help me???

my girls having some problem as you see the top layers they are drooping

However it's only the top layers, the midd and bottom seem ok to me.

i assume this is something light stress or heat stress rather than overwater.

what do you thinnk?

feeding and watering too much. lot of badly burnt tips. the plant is standing up and the stems aren't drooping but the leaves are, classic overwatering. cut back on the feed and let the plant dry out more between waterings

Thx for reply

what about the light distance? don't i need to put the light further upwards as this is not light & heat stress?

i don't think so, light and heat stress look different, the plant doesn't droop a lot, unless its very severe, the leaf edges will curl up in a taco shape, and the edges of leaves will start to look crispy if its bad enough.

Today update

Room temp: 82f

I know already on the nute burn on the leaves, and other than that still my girls having some top layers drooping, which no idea at all .....

Idk, but I wander if there is some lockout going on . Either way I think they will recover with the advice of ^^^^^ there's some good advice from above.

I think i've found the reason, and it seems to me that it was under-watering.
I pour a lot towards at some flush level i thought last night and this is after one day how they look.

they look better than yesterday.

Do you have a fan moving air around in there or are you relying solely on your intake/exhaust? 82° with nearly no air movement is oppressing to the plants.
