that is normal buddy. the plant is nearing the end of its life...it knows. those big leaves stored alot of energy and now it needs that energy.

on second thought it looks like some sort of problem. but i too use botanicare products and use double the dosage your using. if i remember correctly it says to use 25 ml of bloom, during flowering. your only using 8? and 15 ml of LK, and your only using 3? i been using the full doasage and not had these problems. perhaps a deficiency.

As thafoot mentioned, you likely need more nutes. 500 ppm is a bit low especially since most of what you are giving them is addatives. You don't need 15 ml of sweet, take that out and add 15 ml of bloom.
Only going by your first post, couldn't see pics

Your run off is 360 and you fed them 200 4 weeks in you should be at full strength. 1800ppm is what I am running the 4,5,6 week.

Your starving your girls. Get a book and a couple of meters.

Good luck

Well I have a ph meter and Tds meter so everything has been tested. I know my ppm of nutes is way low but the FFOF soil seems really hot. I can't tell if they are burning or under nuted??? They sure look burnt to me though,the two worst plants are the ones with runoff at 5.9 ph.

keep it real. said:
Runoff 5.9 6.1 sounds like salt built up I would flush very well and feed lightly

This drying out of the plant actually got worse right after a pretty aggressive flushing of the plants. Should I focus on just the two worst plants also why is this happening to mostly the top of the plant?

Your plants leaves are curling man so its got a deficiency. Increase your feed but don't go mad.

If it's on two plants and you aren't sure what's wrong then feed one and flush the other. You'll soon find out which works and which doesn't.

I've had something very similar to this on mine, and wasn't sure if it was lockout of some sort or under-fert. I had some other weird stuff going on too though. For you it could very well be advanced P or K deficiency?

Edit: You might want to try cutting down on the molasses too...too much can be a bad thing if you don't have enough microbes to eat all the sugar.

Well I fed both of the two worst plants with 10ml of pure blend pro bloom and crossing my fingers,it sure looks like the plant is pulling all the color from the older leaves all of the new growth is vibrant leading me to thin under nute. Should I cut off the yellowed necrotic growth ot let the plant consume the nutes left in the leafs?

Leave leaves on the plant until the plant has taken all the goodness out of them. Otherwise it'll have to start pulling nutes out of the bud leaves if you aren't feeding her enough.

If them come off easily then remove then...if they are totally dried up and brown then remove them. I'd leave the rest.
