5th Flowering week leaf yellowing change in nutrient program 1 day of tent overheat
GreenEyezstarted grow question a year ago
Last week (4th flowering week) I started with Plagron Greensensation and 6 days later I've seen some serious yellowing of the lower fan leaves. Also leaf tips are turning purple a bit. Had a day of overheating (~29°C) too. Question is, with what am I struggling with here?

If this were my grow, I'd be treating a nitrogen toxicity which has led to a calcium deficiency... and I would be flushing with 3x the pot volume of pH'd water... I'd also be lowering my pH to 6.2 and getting rid of the calmag because that's useless given the reason for the deficiency (too much nitrogen).
Good luck!

Crispy at the bottom suggests root problems to me (bound)... Because your pH seems fine (so long as there's some slight variation every feed). They're in small pots so could be a hunger issue too as they move deeper into flower and crave more PK.
Usually I'd say whenever any issue presents itself to flush and readjust the feed, but I don't think you are overfed... If anything they're hungry imo, but then your feed looks good, which is why I think it's a root thing!

Light or nutrient burn?Ive been having yellow tips on the tops of both my plants for some time now, I already raised the light up a bit higher than the maximum height the manufacturer recommends, but Im still having the yellow tops. Could this be nutrient instead of light burn?

WHAT IS CAUSING MY LEAVES TO CURL? (Day 64 pictures)The leaves at the top of the plant seem to be curling up. My first guess is that there is too much light. I recently moved my light down to 12 inches above the canopy. The PPFD should still be under 1,000, but I don't know what else could be causing it. Please help. 🙏4 years ago

Spots and yellowing on the leavesGood evening I have an autoflowering at the eighth week and recently yellowing has begun to appear on the leaves that I don't understand if it is the leaves that go towards the natural end or a problem of burning of fertilizer or even a fungal infection.

Help diagnose hydroponic plants! Too much light/heat? Nutrient issue?The plant's leaves on the right are wilting and drying out, while the leaves on the left are spiking. Just did a nutrient/water change but it didn't help, and it looks like growth is being stunted on the right plant. Humidity has been around 45-55 rh and temp 70-80F

Nutrient deficiency or surplus?Hi Guys will post a pic shortly. Have to update the grow as we are actually heading into week 6. One of the white widows is a fair bit smaller than the other. And is showing some form of difficiency or nutrient burn. I think it may be due to to little phosphorus. Opinions?
