Hey guys,
New member to rollitup but have been here plenty of times for answers and want to thank everyone for all their help and support! Now my issue..
These photoperiod plants are in their 5th week of flowering now and just starting last week i noticed a yellow fan leaf here and there, wasnt too concerning just wanted to keep an eye on it. Buds are still growing thick like normal, normal spacing between nodes, even with new growth. But now, on two or three of these ladies im noticing the veins staying a nice green while the leaves are starting to turn bright bright green then yellowish then burnt (looks like light burn but ive already ruled that out by testing it. Ive also ruled out not enough light as i turned my #marshydro FC-E3000 up a bit and observed actual light burn )
Ive narrowed it down to potassium deficiency ( because this happened so late into their flowering) or magnesium deficiency. I dont believe its magnesium deficiency because every feeding i give them the recommended dose of CaliMagic (General Hydroponics) as i have always done with every cannabis plant ive grown and have never seen this problem before. Ive been searching tirelessly online for days now and really cant make a decision as i dont want to harm the plants anymore so than they already are but at the same time i dont want them to croak out on me. I run the full GH 12 liquid nute line minus rapid start and diamond nectar with a few different microbe additives. I did flush the ladies that were showing these signs with pH’ed balanced R.O.’ed water two times back to back and then gave them a light feeding going a easy on the nutes, which didnt seem to do anything. Temp stays between 73 degrees at night and no hotter than 79 degrees with the lights on. RH stays between 60%-65%. Any suggestions, tips, or advice would be GREATLY appreciated! Thank you all in advance and happy growing! Stay lifted and stay blessed! ️
