I thought they were about 3 weeks old.. they are actually 3 months old! I can't believe how long ive been having them lol.. so Im flowering soon as soon as this problem resolves. I have been feeding the ebb flow at around 650 ppm and I raised it up to 900 48 hours ago and its 800 now. So i think theyre eating a bit more, I also cut out Technaflora's MagiCal because I ran a nutrient calculator, and using that brought my Cal ppm to nearly the ppm of the Potassium, I read it is supposed to be a 4:2:1 ratio of potassium, calcium, and magnesium.
I added MagiCal because of a MG def early veg and it fixed it, but they started having this problem slowly, the brown patches on the leaves, it doesnt matter how close or far they are from the light. The white stuff on the leaves is from spraying sulfur fungicides and another one, after I thought it was rust fungus since I havent been getting right guesses on here..
I switched to DynaGro Magpro and now the ratio seems to be normal, I have the MG without the tons of cal from MagiCal.. do I seem to be on the right track? It looks a lot like the Boron deficiency pictures Ive seen researching for the past couple weeks.. would bringing the ppm up like I did and getting rid of the tons of Cal help? or do I have to flush the system if its a nutrient lockout from cal.. idk! Please help me and throw around some insight, I need to learn whats going on!
The cupping/tacoing leaves seem to only happen on the GSC (far left) and the Liberty Haze (Far Right) it is NOT heat.. and def not light burn as has been suggested.. they are not directly under the light and are far enough from it.. and I have a pic of it happening under the screen as well.
(TLDR)
Just realized plants are 3 months old. So far, steps ive tried, is lowering ppm to 650, didnt work, seems to gotten worse and they started losing the dark green color to a lighter green, kept it at 650.. sprayed with sulfur fungicide, didnt work, so I tried a harsher one, daconil, didnt work.. and now Ive done a rez change, upped ppm to 900 (down to 800 now though, they ate) and switched MagiCal to Magpro without extra Cal. Waiting to see if it works but can you help diagnose?
Hey guys I posted a different thread and it seems like I fixed some curling with a fan in there but it's still cool temps, and one of the strains still curls but not as bad..
