maybe high temps. ph might be alittle low at 5.5. i haven't grow out that strain so anything is possible.

 

[Core]

check if there is any slime or thick gel on them brown roots?...maybe a beginning of rot in the trays...or maybe some water remains after drain...that ain't good ether as far i understood ...

also lower the nutes a bit 1600 is a very strong diet !!!....and while you at i it you must get the ph a bit higher up...bout 5.8 for optimum uptake...

Hey bro....

Couple things I noticed off the bat (some already stated).

EC 3.2 - WAY WAY WAY too high...especially for only 2 weeks in flower. These might be heavy feeders, but they wont until maybe week's 4-5-6...

I also use Floranova Bloom... that shit is STRONG. 8ml per gallon is as high as I dare take it, and even then I will get some weird burning signs (leaves twisting, folding, browning, etc). I would HIGHLY recommend you dump that rez and begin again...

FB also has a good amount of Cal-mag already in it (unlike pureblendpro products) - so until your ladies tell you they need more, I'd stick with JUST the floranova for now.

Try dumping the rez and going with 4ml of FB per gallon... should bring ya up to around and EC of .8.... then, every 4-5 days when topping off, add in another 1-2ml per gallon until you reach maybe 1.5... keep it slow and steady...but again, an EC of anything over 2 is really pushing it IMHO.

Additives - Personally...I would drop them for now....at least until you know what to expect from this strain. Right now, they're just overkill.... Like giving a kid a 32oz steak and then dumping whip cream and peanut butter on it....

pH - this needs to be in the 5.8-6.0 range if you can manage it. With all those additives I'm sure it's hard. But if you go with your R/O water and a lower dose of ONLY flora - it should balance right out and require little to know adjustments.

looks like a little nitrogen burn. id definitely dilute your nutrients, great advice up above.

thanks

thanks

bud love: thanks for the advise bro. deffinatly dump my res and now my levels are way lower with a ph of 5.8... and new ac unit installed to help with the hot days here.
thanks to core, scf, and wish


ill keep you posted..
thanks again

The leaves (and plant) are stunted from too much N. Since your EC was too high that meant your N was too high.
Small and dark green= stunted
When temps rise, transpiration increases.
This means a lot of water is being absorbed and evaporated from the leaves.
When this happens, the salts (ec) in the soil increase and also in the leaves.
This means if the nute concentration was correct when there was ample water the nute concentration will now be too concentrated (resulting in a higher ec) because water is being evaporated out of the plant faster then the intake of nutes, resulting in a more concentrated nute solution.

In other words folks, when it's hot don't feed so much.

Excellent point Inflorescence.

When manufacturers print up nute doses and schedules, you have to know that their grow rooms are much better than yours, with much more light and probably near perfect conditions. They base their info on their own rooms.

Now chances are your room is gonna be much smaller, with much less light, so you have to take that into consideration when dialing in your own nute schedule. Plus, it depends on strain, temps (as Inflor stated) and light. The less light, the less nutes.

Yes, Less is More!
