a few plants i have are forming a few yellowish leaves. is this caused from too much nutrients? im growing a batch of trainwreck. what's the right heighth to switch my lighting cycles? opinions please.
you need to tell us much more about what type of growing environment you have, what type of soil you use (if any) what size the pots are..etc... as for when to switch light cycles, that is up to the plant. you should wait until it is sexually mature. It also depends on what method you are using to grow your plant. if you give us the info we need to help, we'd be happy to.
growing environment: backroom w/ proper roofing ventilation(no attic space. no ceilings. just bare wood.). i have a 6 site basic tube system. im growing in hydroton under a 400w HPS light. this is my 3rd time around. im seeing how much this forum can actually help me this time around as well. as for the leaves, they're looking as they should now. its been a month and 2 days since i planted this batch from clones. i need to purchase a new camera to take some pics. im sure that'd help out alot more too. i also just started some more clones today: 6 blueberry 4 purple urkle im growing these ones in a waterfarm system. 8-2gal buckets. 2-400w HPS lights. im sure most people are familiar with this system. im curious about ventilation. what kind of fans do i need or should i use? california summers aren't the coolest, and its right around the corner. this is something i should probably take care of pretty quick.
