Leaf Issues

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?

no i need to test a run-off... probably gonna pick up a new PH meter tomorrow. i shoot for 6.4 to 6.5 for PH reading...

so you have never metered the medium or the water?

no no no... i meter the water every time i add nutes, i am having some issues with my meter right now, it's slow to hit it's mark, batteries may need changing... but it has been a long time since i checked the run-off

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?

Pro-Mix and Fox Farm

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

recommended, but giving a little less over the last week... thinking about flushing everything

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!

appreciate the help budz... lot of useful info. cheers!

Actually neither have I for that matter, But then I am lucky I never really had a need to. I think our friend does.

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!
