heat stress slowing development?
GrowingGrannieanswered grow question 2 years ago
First of all, plants are individuals... each one may react differently to the same set of conditions than the others. I don't understand the diagnosis of heat stress here - the temps are just fine - but I think your pots may be just too small and its the ROOTS that are getting too hot. 1/2 gallon pots aren't going to do your girls any good at all... pretty certain they've become root bound and this will lead to increasing difficulties... time to repot?!
Good luck....
ClydeGrowsanswered grow question 2 years ago
You have two different strains in there so they'll respond differently to the same stimuli... Even the different plants of the same strain will grow differently. Best bet is to move them around the tent, if you can. Same with the fans if possibleee. If I have differences in the same space, as I do in my grow right now, I'll put the shorter plants on a plinth of some kind and raise the whole lighting system. If you can get multiple hygrometers that will be a good shout, so you can see if there are any differences in temp and humidity in specific areas of your tent. Good luck!

5th Flowering week leaf yellowing change in nutrient program 1 day of tent overheatLast 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?

Yellow leaves near the harvestThis would be my last week of fertilizer watering. And the plant has the leaves turned to the side and with yellow spots. Sign of lack of zinc? I would start making the flush from Friday, is it recommended to start now? In about 2 weeks I will harvest
(I tried to water today)

Leaves curling on sidesOkay so the leaves are acting weird and kinda curling in on the sides. Like it's heat issue. I think maybe to strong LEDs. Idk.
It's only 79°f
Light (ESv300) is on lowest setting @32in away.
Fed GH flora trio. Only 237ppm.
The leaves are also yellowing between veins.

Kolas folding upwards?Some of the tops of some colas are stretching up and not flat to allow the pistils to form correctly. almost looks as though they are stressed - I have had similar things happen with other tents and had to remove the plants in the end. How can I stop this?

Yellow and fragile leaves 2 weekCouple leaves yellowing and bit curved up. I suggest there can be the options: 1) magnesium deficiency; 2) nitrogen deficiency; 3) Light burn.
For case it is magnesium deficiency I sprayed the leaves with magnesium sulfate (solution - 1g per 1 liter), but it won't help.

Magnesium Deficiency ? How can I fix it ?got a little deficiency (maybe burned? but I think not).
I'm pretty sure it's magnesium's deficiency, it happens after a flushing. I added 2 times the last 2 weeks a little bit of CalMag (BioBizz, but ive bought it 2 years ago, maybe it doesn't work well idk).

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

Nitrogen toxicity and tip burnSmallest plant (1st pic) was showing nitrogen toxicity and I just fed distilled water at 6.3ph to try and help. Bigger plants had some tip burn and curling up. Thought this would help them. Any tips on how you would treat this please?

Strain starting to canoe any ideas?So I have 3 plants of the same strain SSKM. 2 of them are starting to canoe. 1 of them has no discoloration on the edges of the leaves, the other does. 1 without discoloration is in coco coir, other is in soil. Don't think it's over watering or underwatering

I don't think this is nute burn...So I thought I had a case of mild nute burn but I haven't given the plants any Bloom or Calmag since last Friday, only water so I'm wondering if this is a nute burn issue now. Could it be my PH? Last I tested my run off it was at about 6.65. What's causing this?
