Thank you for your reply. I will do as you said immediately. When you say top them. Is that the same as super crop?
Happy to help. ;)
Topping is cutting the top off, supercropping is crushing the stem and bending over. LST is gently pulling a branch horizontal and tying it off.
My nodes look great. It's the huge fans turning brown and drying out.
Likely a combination of pH issues and possibly starving a bit for nutes. 500ppm is a bit low in high light conditions.
Too much air can be a problem. Turn off the pumps for an hour and see if your pH drops. If it does, there's actually too much air going through the solution.
ph at 6. Nutes at 500. Actually using RO water so I add cal mag to bring it up to 200. Then nutes as it says brings it to like 350 to 400. I just bumped to 550. I also am using
current culture h20 for my nutes. Along with UC roots.
pH at 6 is too high. Full nutrient uptake happens when pH rises from 5.4 up to 5.8 and then dropped back down to 5.4 using nutrients.
Cal/mag?? The
current culture h20 mix you use is low on calcium and nitrogen for cannabis? You checked their nute calculator (hopefully they have one) and are mixing for what cannabis needs, yes? Epsom salts are usually all that's needed for dealing with the magnesium variable. The sulfur in it is good for terpene production as well.
There is zero need to add cal/mag to r/o, simply because it's r/o.
My roots are bright white with green roots coming through the pots. No smell. Just added photosynthesis plus. The plants woke up nicely. But I'm still not out of the woods. Hard to control my water temp. I'm trying. It's at 68 now but I've seen it climb to 73. Ugh. This is all cool as it's a learning experience. My bulb is a
hortilux blue 1000 watt. Just swapped out my flowering bulb yellowish as I was told. I'll send a pic of my set up. Please keep the suggestions coming.
Keeping the 68F stable is massive. Even a few hours of high temps will impact yield.
Swapping bulbs won't make much of a difference until everything else is in line, no worries. Drop the pH down to 5.4, bump the nute solution up to 600 and then watch the pH slowly climb. :)
