It is just plain ProMix HP. Didn’t add anything to it. Using Remo Micro, Grow, kelp, CaliMag, and Terpinator. 6ml of each in 1 gallon (4litres) of water. Use this for each feeding. 1 gallon per plant.Leaves curling up a bit and dry on edges
Any idea what is causing the leaves to curl a bit on the edges? They are sour diesel growing in coco and perlite with a recirculating drip system, hlg 600R light about 36 in above and about 60%. Ph is 6, gh flora series 3 part nutes With cal-mag as well. I have a small fan that runs 24/7.www.rollitup.org
I was gonna write it up again specifically for your situation but it's better for me just to link you to this other thread. Is it possible your soil is over alkalized with too much lime, dolomite, rock dust, beef bone meal or some other alkaline input?
Will pick up some EWC today. BUT should I wait and apply when the soil dries up and I’m ready to do the next water/feed? And for the next water should i just go straight water?Not broad mites.
OP I think it could be a true boron deficiency per your description of setup, instead of a lockout due to other conditions. Pro mix is essentially a sterile soil-less medium. Just the peat, coco and perlite. Idk for certain but a lot of micro nutes don't contain boron, I would try to aquire a micro solution that states that it contains boron. This one is proprietary, ie they don't say what's in it. There should be a tiny amount in the kelp tho...
Some people would shy away from this since they are familiar with it as a cleaner and fire retardant, but borax can be top dressed, but the rate is like 1tbsp/50 soil gallons. So microscopic for smaller pots.
Also, could be exacerbated by a lack of biology in the soil? Top dress with worm castings, make a good tea with some molassis, compost and imo?
Looks kinda like russet mite damage.Hey everyone. Are these still looking ok? Outdoor grow for the first time. ProMix HP and using Remo Nutes at 800 PPM for feeds.
They look weird. Any ideas?

Can this be fixed?Pretty sure you have "black death" disease as described here https://www.icmag.com/forum/marijua...ry/323206-help-identify-black-death-in-hawaii

The chewed up looking new growth and purple tinges are tell tale signs of it...
If thats the case the plant is experiencing a radical hormonal shift and any signs of deficiency or over abundance of any nutrient has to be ignored because cannabis leaves behave extremely strangely in revegged plants.Not sure about that one top but I do see some re-veg leaves..
