I had same issue, flushed for 4 days and it was worse. I would maybe still feed them, just lay off the PH, keep around 7 IMO

How they look?How are my ladies looking? The ones on the left are norther lights, they are looking very lime-green. Any thoughts on why that would happen? Also the wedding cakes in the back seems to be slow to get bigger, I wonder why?

Leaves fading to yellow I just changed the light cycle to 12/12 - My leaves are fading to yellow, at first just new growth but I see it on the older fan leaves as well. I did give them a flush and only ph balanced water for a week and a half. Also, just gave nutrients(50% strength ) 5 days ago

Over the last week, I have noticed quite a lot of yellowing of leaves, along with them drying out and getting brittle. Now that I am checking the PH of the nutrients, and adjusting to 6.0, I have no idea what's going on. Any insight as to what the issue may be, is appreciated.

1st time grower - nute burn? Lockout? Potassium def? Light burn? HELP PLEASE Experiencing some deficiencies/light burn/heat stress. Says SSH likes hot/moist climate. Plants are planted in FFOF Soil, fed them 15oz of nutes yesterday. Using advanced nutrient systems, see above. Light is a SF1000 LED meant for a 2x2 tent. Would that burn them hanging at 20”?

Calcium / PH issues? Did I take the correct steps?Am I on the right track to remedy my plant's issues? Seems like calcium deficiency to me. Soil test comes in at just under 6.5, my reservoir water going in is 7.3ph, in case its actually a lack of calcium and not the PH i've top dressed gypsum (and epsom salts).

Can't deal with yellowing leaves in 4th week of flowering Been having this problem for a few weeks. I suppose its deficiency of Mag and for the last week or so I've been giving increased portion of CalMag (for 1.5l of distilled water TriPart grow 2.1, micro 2.1, bloom 3, Calmag 12ml). Should I give them more time or its something else?

Issues with leaves. Day 90 total, 30 of flower. Leaves have been getting more and more yellow the past week, with progressively more brown tips.Vpd has been pretty close to ideal, the pot had 1 gallon less soil so could be missing out on some nutrients? Possibly Potassium? Otherwise not sure what it could be. Does not appear to be N deficiency because the leaves are affected from the top too. What should I do to fix this
