Short n sweet. How about this..........

can some1 please tell me whats wrong with my plants just by looking at these pics?
Lets see who's got the skill.
I know whats wrong I just want to see what you know
kidding..im scratching my head badly over this one. ?! I'll narrow it a little, soil, 400watt hps 1ft away (27.1C max at plant top), temps 22-27C, 177CFM, sog grow space 2x2x6ft, flushed after 1 month veg, fed 1x full strength flower nutes 14 days ago, watered thereafter and flushed again. Not over watering/under watering. No bugs. PH 6.5.

peace

Don't think your on the right track

[FONT=&quot] Boron (B) is necessary for cells to divide and protein formation. It also plays an active role in
pollination and seed production.

[FONT=&quot]Boron (B)[/FONT][FONT=&quot] - From slight chlorosis to brown or black scorching of new leaf tips and die-back of the growing points similar to calcium deficiency. Also the brown and black die-back tissue is very slow to dry so that it can not be crumbled easily. Both the pith and epidermis of stems may be affected as exhibited by hollow stems to roughened and cracked stems.[/FONT]
[FONT=&quot]Yellowing - Upper (New Growth)[/FONT][FONT=&quot] - Yellowing of the upper (new growth) of the plants could be a sign of a Sulphur (S) deficiency. Sulphur deficiency is pretty rare but usually start off as a yellowing of the entire ‘younger’ leaf including the veins. Other signs of sulfur deficiency are: Elongated roots, woody stems, and Leaf tips curling downward. **Note- Most yellowing of the upper leaves is a bleaching from being too close to the lights.

Solution - Check and adjust the pH level as necessary. Check your fertilizer/nutrient levels and make sure you are giving the correct amount/type for you particular stage of growth. Also a good test to see if your lights are too close is to put your hand between the light and the plant. If your hand gets too hot for comfort, the light is too close and needs to be moved up higher.

I agree with you. Its not Boron. doubt its a sulphur issue as I am feeding a multifeed for flowering. My guess the full strength was too much for them. Leaves are slightly brittle and clawing+twisting on new growth. All old leaves are still lovely green and no curling downwards. I did flush yesterday and if I'm not mistaken it seems to be losing some yellowing and relaxing on the curling. Thanks for your input.

I am guessing big boot of flowering nute kicked its arse so early into flower. I feed mild veg right up until a week or so into flower.

I would say lockout, I dont have enough info to say what but the fix is the same either way. Flush and rewater with a milder mixed feed including a trace mix of some kind.

Whats the latest runoff ph ? has the flowering nute knocked it down at all ?

Thats all IMO though, What nutrient range are you using ?

Bah you beat me to it

What you mean bah you beat me to it? the answer full strength too much so flush? I will check the ph runoff but ph needle in soil says 7. I would say lockout yes. I think thats why flushing has helped a little already it seems. I will post the progress on that. Thanks Mouse.

Soil PH meters (the type you have) are extremely inaccurate. I think you have the right idea and I am sorry if my scrawling posts are a little hard to understand.
