@BonusPackage Magnesium deficiency You may need to raise the ph up a bit between 6.2-6.5 would be ideal
This will allow all of the nutrients to be absorbed better

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.4y ago

How do you harvest in hydro (drip system with a tank) when some are late ?Half of the plants are late (chlorosis, iron toxicity, nitrogen overfd) on a scrog net. As individual flush is impossible, I guess I have no choice than having different batches of ambered trichomes ! And I thought about different strains next time, sweet dreams...4y ago

Leaf problemsMy leaves are getting yellow from the bottom, and some have burnt tips. It started when she is in flower.
I often feed Powder Feeding from Green House. PK+ (NPK: 0-30-27) and Hybrids (NPK: 15-7-22) the PH is 6.5
They say this strain wont need much nutrients but can handle more2y ago

Strange leaf deformationHave these strange leaf formation on some of her blades, looks liker the main vein has somehow outgrow/stretch, with no actual green stuff around lol. Several leaves have this. Combined with a slightly general canoeing, could it be from a nitrogen tox ? Growing good though
