Heat or deficiency? Or something else?

RamboGringostarted grow question 4 years ago

I'm noticing some sort of deficiency or toxicity. I need help on figuring it out. I water with distilled water, cal mag, and 1/2 strength bloom boosters. Ph @ 6.5. Could it be heat? It gets a little over 80 F. I have AC running, It's still cooler than outside in the sun though

80F isnt high enough to hurt them, its on the outer range but fine if thats the real temp at the leaves. Weird things I have to go to the water, distilled has no minerals in it and thats not bad IF you add them. THats why I put up with tap water. see some CA damage and the leaves are very dark but I am unfamiliar with the strain. Could back off the PK booster see if its causing issues. You da man, good luck

Looks like nitrogen overload. There's probably a buildup of it in your soil. The plant doesnt need much right now either, so what was fine in the soil now is much different than 2 weeks ago. Test runoff and flush if it's hot. Then restart your feeding program. Also, don't find out the hard way: too much P will block your calmag so if you start getting yellowing and brown spots on top growth, that's likely the reason.

Harvesting a struggling plant or just letting it fight Can she be saved or just flush her and harvest what I can? She doesn't appear to be happy. Has some CBD genetics so the lack of trichomes don't worry me. Rest of my garden is fading as well. Flushed em last feeding and they didn't seem to like it.

Burnt looking seedling What's going on with my #2 seedling? I thought it could be light burn and raised my light by 4" but the odd coloration on the tips has gotten worse 18hr later. It also doesn't seem to be drinking whats in the coco yet so I'm cautious about feeding.

Weird leaf It seems one of my leaves has become very oddly curled up. It has very slight brown spots with a strangely curled up tip. As seen on Week3-day19. Can anyone identify some sort of problem like excess or deficiency of nutrients?

Spotted crisp leaves What's up with these leaves? They've all been spotting up, crisp edges and tips curl. I keep flushing them and it helps. I feed them 1 tsp calmag to each gallon and often the mixture gets diluted as much as half. PH water was 6.2 but soil 4.5. 15" from 70% light.
