What could this be?

Hey all, the plant is about aweek and half into flowering, feeding greendream nutes (bloom) and budstorm additive, i have had afew problems with it over the last few weeks, started off with the new growth on the growing shoots were a very light green, the i got ph lockout and it wouldn't move from 7+ no matter what i seemed to try. then i found out that sulphate of ammonia' so i put 2 tsp into 1/2 ltrs of water, left it for 2 days then i took a runoff reading just now and its 6.5 on the button but the leaves are like they are in the pics. i was woundering would where the new grow was light could it have been the start of an iron def?
What is an mj plant classed as, tree,shrub,? (thats been on my mind for days now lol) if anyone could give me some thoughts and a way to go in i'd be really really happy and gratefull. ive put so much time into this plant i'd really like to have a smoke off it this you know what i mean lol
thank guys scunk, ps are plant tonics anygood for cannabis plants?

Forgot to say ive given it afew drops of superthrive, thanks everyone

It a C(3) annual. And your C(3)s look pretty cooked. Sounds and looks like a classic case of chasing runoff pH. Only causes more issues in most cases.

Thanks man, what do chasing the runoff mean? so had up on the ph runoff, everything else got out of hand? should i kill it?

be careful using ST with cannabis... very easy to burn the roots using that shit.

if you must use it, only use very very little amount.. I'm talking about like probably no more than 2 drops per gallon of water.

anymore than that.. and your going to get issues eventually. Might not show immediately or even the first week or so after using it.. but eventually the damage will

eventually begin to show. It won't be pretty either..

good luck though.

peace.

My ventilation is ok, my door is just a black out sheet, my daytime tepms are 72-75, nighttime are 68-69 humidity is 50-60, mostly 55% which says dry on my therma hygrometer, the has afew leaves like in pics but not all plus theres lighter green in the growing shoots,

What does ok mean? Do you have active ventilation or not? What is your light set up?

I got a 3 speed fan blowing outwards from the back of the room, which i next door to a room with a window in' if thats what you mean, the plamnt hasn't been in my growroom for the last few days.
My other plants are doing well in there so i cant see it being that. i give it some miro nutes the other day so would that have done it? my lighting is a 125w cfl on, a box with 3.3 fott flors at the back and at the sides there 2 28 enrgy saving propagator lights haning each for the light to hit the bottom leaves. i got a 600w with a ballast for flowering' its got a dule spectrum bulb which says it can be used through out the full grow but i was told that flors are better for vegging.

Sorry bro, I don't know what to tell you If I had no info just the pic I would say the plants are under weak light (stretched thin growth) or have a fan blowing on them too hard along with some heat stress. But that does not jive with what you are stating. I never used florescent bulbs, but it sounds like you do not have enough.

Good luck, hopefully someone else will pick this up!

Yeah no probs my friend you give it a shoot lol, really gratefull for your info' scunk

If all your other plants are doing good than I would cut-out all the nutrients, flush the plant with PH adjusted water and then just keep watering it with Ph adjusted water until it regains its stature. After that the only real nutrient you absolutely need is phosphorus for flowering, if that!

Otherwise, I would say it has some high heat stress, possibly!

would it help if i put it back into vegging? im not worryed about the buds because of secondry buding?
