Running into some leaf problems. I have already looked into the leaf threads and tried to diagnose it. Looks like N and K deficiency. Happening in Veg. and Flower right now. Maybe a PH imbalance, but growth is incredible right now. Any ideas or thoughts would be appreciated. Thanks in advance.

Well, TBH I am guessing micro-nute deficiency. Z, Fe, and Mn. All 3 will get locked out in higher ph levels. have you checked soil ph?

Well, even still the soil ph can still be too high even if the water going in is correct. What medium and nutes are you using?

Both good products, have you been giving them recommended dosage or less?

May not be a bad idea at all. If it were my grow, I would flush it and let it get good and dry. Then I would start feeding at 1/4 dosage feed, water, water, feed going up by 1/4 dose every 3rd feeding until they reach full dose. I would also if I had the money invest in a ph meter that tests soil ph as well as water and R/O. Best of Luck!

i'd flush your plants for a couple waterings with plain water it looks like either a a ph problem or overdose problem imo

just wanted to do a follow up for anyone interested...

talked and met with a few growers today, they took a look at the leaves and they thought it was a lockout as well... using pro-mix (a soilless medium) we want to shoot for a 6.0 to 6.2 mark, they compared pro-mix to a hydro setup (figuratively), picked up a new PH meter from the hydro store and i am gonna do a massive flush on all plants tonight... thanks again for the help and advice, cheers!
