The first pic is a very "average" plant in my collection....short bushy with fairly good health.....the next pic was the big growth and recently started forming small curling spindly leaves...the 3rd is the lightening of the green between veins on the middle leaves of the tall plant....the 4rth shows all the preflowers (for not looking good it's hairy)....the 5th is a bushier plant with a twisted tip on a fan leaf....the 6th is the tall plant with the dryer leaves curling under at the edges.....the 8th shows new groth color next to old growth color also the leaf margins are curling up on the old growth...
So all in perspective I have curling under, twisting, curling up on the margins, interveinal color blotch, spindleing and drying of leaves. hmmmmmm all dictated by size and preflowering rather than strain. Now what....do I treat the plants as a whole or individually....I have a feeling they are right behind or a little ahead of one another if that makes sense and to treat as a whole. again many thanks and respect for your time.

bonbon....is white vinegar ok to use as a ph adjuster or should I buy a product specifically for that use....I am also using an aquarium ph liquid drop tester, should I spend the money for a more reliable tester? Also do you think I should give my plants a dose of bloom formula 1.5-4-5 just to be safe or continue with my veg 3-1.5-4 until I induce flowering? I can't tell if I need phosphate.

they contain the micro and secondary trace elements,i would use it(bloom) on the next feedings,as far as a ph down,i use nitric or phosphorous acid,I've never used vineger,aquarium testers are fairly reliable, If i may make a suggestion,"pyrosol"from general hydroponics is an excellent additive,it contains most of the necessary micro &trace elements,and is a good soil conditioner,....bonbon http://www.altgarden.com/site/additi...s/pyrosol.html
