You have nute burn. Test runoff and flush if runoff is hot.

Getting out of the ideas - VPD, nutrients or deficiency?I'm getting out of the ideas as the foliar symptoms proceed.
Lowered EC down to 1.8 from 2.2, pH in range.
VPD is getting problematic as the plants seem to be respirating a lot during the day and it rises tent RH sometimes up to 70% - exhaust duct fan wont keep up. Temps 22-24CLeaves. Edges burnt

Calcium deficiency?I'm not so sure if it's calcium deficiency, what do you think?
Watering 100ml of water minimum.
Using 1ml calmag/per 1L(and other nutrients like N,P,K)..soil comes nutrient free.
Should I water her more and add more calmag or is this a different deficiency?3 years ago

Help! Why are my leaves turning yellow?Not sure why some of her leaves are yellowing on the edges.
Is this due to environment?
- 78.3°F | 64.8%RH
Or a watering issue?
- Currently she's drinking 8-9 cups a day through a sub-irrigated planter (EarthBox).
Or maybe a deficiency?
- See Logs for complete details.Week 10

Add nutes or to much?I don't know if it's a heat thing or a need more nutrient thing or too much nutrients. I have only added nutrients twice and it was measured out. I tested the soil with a cup of soil and five cups of distilled water the EC and PPM were almost non-existentLeaves. Edges burnt

Nutrient deficiency which kind and/or light burn?Do I have some nutrient deficiency or light burn or maybe both? Looks like maybe P or K? I changed my light to a HPS and the plants grew much closer to the light so could be too much PAR/heat so I raised the light. I also had started to add Cal-Mag to my feed just before.3 years ago

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.😅Leaves. Edges burnt

Did I do the right thing? Pls check my update on this week!Can my Growmies check my update on this week please? Ppm shot up and I noticed nute burn. Weird bc I have only added water since last week. I cleaned the pump, removed air stone and lowered ppm. Definitely seems like too much nutes - hoping they’ll perk up.3 years ago
