I am gonna say it's a lack of proper run off. I see toxicity and deficiency at same time in pictures. You should get 20 to 30 percent run off unless it's coco. Then it's a lot more, and ph sensitive. Test ph, and tds of run off.

To me it looks like you overdone , just i am lost, is this nitrogen or phosphorus excess.
Would bet on first more.
Any recent big feed ? Plants dont show symptoms of long overfeeding, think it happened recently

Copper deficiency.
Adding a dose or three of a soluable "trace element" mix to your fertilizer routine should solve the problem and boost plant halth in general.

Lockout during transitionJust a random question. I'm growing in a tent using coco and perlite. How do y'all keep your plants from getting nute lockout when they go from veg to flower? I seem to have this problem with every grow, no matter what I try with them.
Thanks for any tips.

They were slightly overwatered, the soil PH of 7.1 to 7.3, lacking phosphorus, maybe magnesium to. Branches from the sides are stretching, but I noticed thet lower leaves started to turn yellow a little at both. If anyone knows good advice to help them out, I would be grateful.😅

Day 38 autos: is this nitrogen deficiency or something cal mag could help with?Kia ora whanau,
Each of my three flowering autos (the Herbies Beginner Auto Mix #1: Ape Fruit Auto, Purple Chill Auto and Godzilla Cookies Auto) has an issue with yellowing older leaves. Do I need more nitrogen or is this potentially something cal mag would address? TYVMIA!

We've had some really warm weather the past few days. This morning, just before the lights switched off, i saw it was 31.1 degrees C in the grow tent. Are the yellowing leaves a concern? The yellowest leaves are really brittle. I don't believe they're under-waterd.Week 13

Lower leaves turning yellow and getting crispyLower leaves are still turning yellow/brown. See photo. A couple weeks ago I got a greenhouse to protect the plant from the rain. Outside temperature has been lower and there hasn't been much sun (mostly clouds) so I don't think heat is a problem anymore. Don't know the pH. Help!

Nutrient burn?Hello I have one plant with yellowing leaves that are also curling downward. Only one plant of 6 has this problem, I suspect maybe this one is just sensitive to the nutrient rich soil? I am using fox farm happy frog and have added no other fertilizer. What to do, flush all?
