Help! Yellowing new shoots

[BC*Dankster*]

Hey everyone, I am 3 weeks into flowering and alot of the bud tips are light light green and some are going yellowish. Some of the leaves around the affected areas are starting to get bleaching in them? Just a really lighter green then the rest of the leaf. ANyone know whats going on....was thinking more nitrogen, more cal/mag or sulphur? We feed , feed, water. Do you think we are flushing too much nutrients out when we water? It seems the taller plants have this problem more than the shorter bushier types...

its not nitrogen. are you PHing even when you flush? they do not look hungry, and it looks like a sight early sign of burn at tip of leaf on a few, no? lockouts are usually either PH issue or too much of a certain nutrient.. dunno anything at all about your setup as you didnt give us any information to work with but I'd verify your PH (calibrate meter too) and evaluate to see if you should lower your PPMs

thanks Ghost, sprinkled a quarter cup of dolomite lime on the top of each pot and watered> Hope this corrects my ph inbalance, if that is what it was. How long u think til I see a difference...3 or 4 days>?

bro no I'm not sure you understand. I'm talking about the PH of your WATER. are you PHing your water and or nutrients that you're giving to the plant?

hard to say on details of when to expect a result bro I'm a DWC guy my medium you see immediate results soil experience may vary. but, to be certain, your leaves will never "heal" in the snese that they correct the damage, the best we can hope for is healthy new growth, increased vigor, no more signs of whatever the fuck that was, and an extra beer in each man's cup if your corner market closes too goddamn early

The nutrient solution is always Ph'd to 6.2-6.4. This is the second run with these strains, and the only thing done differently is that the medium was flushed with some liquid that got mixed into straight water to kill thrip eggs. That was 2 weeks ago , wonder if that stuff made this happen.

sounds like yr in soil if you've chosen the sprinkled dolomite route. about a week for this to start showing effect.

BUT ... assuming yr in soil there's a need to know its pH. pH meter is best but soil test kits (cheap) work well too. altering pH like your doing is dicey if you haven't got a base-line pH.

otherwise flowering cannabis needs N and Ca as well as K. but yr nutes will have this covered ... ?

your explanation could totally explain what we're seeing. any input as to what product you used or the active ingredients? based on the time frame it seems entirely possible - did you PH the time you mixed the thrip killing stuff in AFTER adding it? sounds kinda like maybe the ph got adjusted by the thrip stuff which caused lockout?

hey for what its worth if you have trouble with thrips again, you can try azamax as a foliar method of addressing, so you dont have to adjust your feeding regime - just a suggestion.
