Hello guys, I have a little problem VPD is a bit too high for the moment. End of week 2 flowering and my leaves look like this, I think I will flush for now. Two different tents, the burnt leaves = high vpd
Leave deficiency = other tent ( vpd +- 1.2) what does she need ? Pls help

Oh! And as for VPD get an infra red gun and check your leaf temp. Mines about even most of the time because I can’t raise lights higher. 1 to 1.6 is ok. Aim for 1.4 in flower and lower temps lower humidity like 24c and 50% or lower humidity

Looks like nute burn as per previous. Flush and start again smaller concentration.

Hi! It's a P-K deficiency, caused by an excess of nitrogen, so do a nice flush, and as soon as it finishes drinking, water with only flowering fertilizer, but at half strength :) next time if it's recovered you can water with a full dose! Happy growing!

Looks like a nutrient burn to me, I'm not an expert so maybe wait for someone else to give you an opinion. I suggest to flush (you have to do it properly, using PhD water 6.5) then wait some days and restart with a light feeding.
Good luck!

A bunch of different leaf symptoms appeared over just a few hours, can you spot the issue in my detailed diaries and solve the mystery?Everything was well, until over just a few hours they developed all kinds of symptoms.
I have 2 diaries here for the grow, the 2 called “Grow #2” and I am very detailed about what has been done day to day.
So please have a look and see if you know what might be happening

Harvesting a struggling plant or just letting it fightCan 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.

The leaves are wierd shaped, but growing fastHi everyone! Please tell me, is it a consequence of leaf scorch with light, or incorrect watering, or I was very in vain in the beginning added root booster? The big question is, is it worth waiting for a potential recovery?There's nothing like it at google

Nutrient lock out?Well watered my plants with great value drinking water. Ph 4.11. Didn't check ph until week 3. Currently upping it to 6.5 after I found the issue. Does this look like nutrient lock out? They were in root Riot starter plugs. And I fed the some clonex and great white microbs.

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.😅

Yellow/burned tips & curled leavesI have an issue with some yellow/burned tips and curled leaves.
I already suspect that mainly is from light stress but could also be a nutrient deficiency?
I´ve raised the lights the max I can and keep it at 80% for 20 hours.
