Yellow leaves with brown patches between veins.
Finedakinestarted grow question 4 years ago
Any ideas on what this could be? I checked the PH and it is right around 6.5. I did feed them twice last week as I was out of town over the weekend. When I got back the temp in the tent was °91. It's bad on one plant and starting on another. The rest look healthy.

Looks kinda like boron deficiency to me.
Throw a tiny bit of borax with calmag at it.
sir_isOanswered grow question 4 years ago
91f is exceedingly unlikely to cause that, as I've grown plants without any such issues in MUCH MUCH hotter conditions.

Though boron deficiency can also look like yellowing, curling, weird growth, etc.

Probably got a little heat stroke from the temps but they will be fine if you got everything back into parameters upon returning and they seem happy. It’s a slight toxicity from it having to over perspire during the hot period. The only water it could use was from the soil. Uptakes a lot of water/food. Stoma closes because it is richer cause it’s drinking faster than it would. Very vicious cycle if left unchecked. Glad you caught it and happy growing!!!

Can't deal with yellowing leaves in 4th week of floweringBeen having this problem for a few weeks. I suppose its deficiency of Mag and for the last week or so I've been giving increased portion of CalMag (for 1.5l of distilled water TriPart grow 2.1, micro 2.1, bloom 3, Calmag 12ml). Should I give them more time or its something else?Leaves. Color - Yellow

Nutrient deficiency? Or just getting ready for harvest? Sister plant is very green (different strain, strawBerry cheesecake, last pic)Plant is Raspberry Kush, I’m assuming it’s because she is close to harvest and it’s sucking all the nutrients out. Also, looking up other raspberry kush diaries i’ve noticed they tend to end up pretty yellow. Was fed bloom nutes yesterday but noticed lots of yellowing today.Week 9
