So I currently have 4 plants in flower 2 gold leaf and 2 jack herer. Everything has gone super smooth until about 1.5 weeks into flower when one of the gold leafs started with the yellowing of a couple leaves. Further investigation showed that the leaves get a couple of little brown spots them the leaf turn yellow from the tips to the base of fan leaf. I’m running ocean forest soil, feeding general Organics “go box” newts. I’ve adjusted my feedings up and down with no luck. I’ve also moved my water ph’s up and down thinking it was a deficiency. I water using r.o. Water and occasionally will water with my well water, which is very good by the way. I’ve done cal mag foliage sprays with no luck. I’m stumped!!! All the other plants look good with no problems.....just 1 plant. This 1 plant was by far my “stud horse” throughout the whole grow. Temps during day are 83 and night is 75. The rh is 39-44

Looks like Potassium (K) deficiency.
What is your ph after mixing nutrients?

6.5 after everything is mixed. I tried pushing it up to 6.7 and down to 6.1 thinking I wasn’t getting adequate uptake of newts. I really hope it is a potassium deficiency. Can I foliar spray for that or try feeding more? I’m 3.5 weeks into flower. Thanks for taking the time to reply. It’s nice to have a fresh set of eyes on this issue

Let her dry out. Give her a bone marrow flush. Let her dry out again, drop your nutrient ph to 6.0 for soil. Sorry bro I’m not a foliar spray grower. I always take it to the roots. Up your potassium intake with your nutrient feed.
Hopefully that helps:)

Humidity problem? Please explain? My humidity was constant at 44% since all this has happened I thought it might be humidity so I dropped it down to 39% and it’s still happening. Thanks for reply

I find 55% humidity is the sweet spot.

Did you switch to a high P low N bloom fertilizer?

The dark spots look like calcium deficiency to me.
