Nomorebushstarted grow question 4y ago
One of my plants has started yellowing, my pH/ec pen is broken but have been giving same as before 6-6.9ph,can it be lack of nutrients? It's been a little hot but nothing crazy. Other plant that got same water is looking great tho. Why is this one difrent? All answers appreciated

In my opinion you are at the beginning of a P-K deficiency so I suggest you to use a good P-K 13-14, measure a PH around 6.5 and also give a CAL Mag fertilizer. The plant will recover in few days

This one is needing more P and K.... and since your pH pen is broken, am concerned the pH levels you're estimating are not correct, at least not for her. If the pH goes out of a good range, the plant can't absorb the nutrients it's being given ... so find SOME way of getting at least a good guesstimate of the pH and make sure it's between 6.0 and 6.5 ...
Good luck!

Magnesium - Nutrient problemDo I have Magnesium deficits or any other problem? I started to notice during the last week and it is progressing quickly.
The last weeks, pH of drain water was low (between 5,5 and 5,8) but I could increase it until 6.1.
Has anyone the same problem?
Thanks!

Upward curling of leavesOne of my plants has started to have it's lower leaves curl upwards & started to go a yellow tint that's harder to see in my images. Yellow tint is starting higher up as well I think, but the curling is only on the low leaves. Is it nutrient defficiency, heat stress, wind stress?

Rust Colored Spots on Leaves in FlowerI’m in flower with my Sour Lemon Hash Poison and things were going great until this last weekend. I developed a bunch of fungus gnats on Sunday, and today my leaves are looking like this. How can I safely treat this in flower?
