BROWN SPOTS ON LEAVES FROM NUTE BURN OR DEFICIENCY?
stonedkoalastarted grow question 4y ago
12/7 noticed leaf curl & yellow tips. Thought she had Nute Burn so 12/8 flushed her in plain water + hydroguard ~120 ppm. 12/12 did half the amount of nutes I would minus calmag. Brown spots appeared on 12/14 so I switched her to full nutes + calmag, ~500 ppm. ~45%RH @ 76 degrees

Looks like deficiency, but can also be too much light, check your ppfd and give it a day or two and see how she responds from the feeding you just gave her, Good Luck!

CBG2 leaves curl and fold down WHY? . Potted in fabric bag, seated on 3 stones in drain bin. Receives same fertilizer TPS1 and water schedule as all in tent. Was last to pop soil. Almost 10 inches taller than Gaia CBG1. I thought she was dehydrated from the fans blowing.Week 6

Deep Ridges in leavesI have a whole strain (3 plants) exhibiting a general lack of vertical growth; but also deep veins and ridges causing eveb more malformed leaves. Same setup as my other 3 plants of another strain that are thriving.
Looks like pH issue? Maybe this strain needs lower?5y ago

Is this a Magnesium Deficiency?Hi all,
Day 98. Northern Lights.
1 of my 3 NL girls looks to have a bit of a Mg deficiency. I'm close to harvest so not too worried however it would be nice to have a confirmation for future grows/learning as I'm very much a noob still.
Can anyone confirm/correct me pleaseWeek 14

Leaves have developed "claws" at the tips that bend downwardsMy leaves have developed "claws" at the tips that bend downwards.
I suspect there is too much nitrogen because I probably used too much root juice. (Approx 8ml, scale was inaccurate)
Now my question to the professionals: what can I do to fix the problem?
