Looks like a lockout caused by too much PK. Try cutting back on the tiger bloom. The spread should stop although the spots probably won't disappear ever.

Always diagnose before you react.
Diagnostics 101
Check your runoff ph and ec levels. The two most important factors in a grow. One of thos 2 off and your plant starts to suffer.
Find out what your nute levels is at the roots. If its creeping up more than what your feeding at it is getting overfed and It's causing lockout. If the ph is out then that also causes lockout. Nutes to low and ph is ok, then you know it is a deficiency and not lockout. Cheers

Leaf discoloration on green crack auto ever since she sprouted. Figured it was the fertilizer in the medium and thought she may grow out of itSo 46 days old now. She’s grown bigger than my other autos but she’s shown discoloration on her leaves since sprout. I top dressed her last on day 30 with less fertilizer than called for thinking she didn’t need as much as I amended with. Does it look like Mag defciency?

Leaves doing weird stuffMy leaves on one plant are doing this weird thing where some parts are yellow'ish. It looks like a mutation. She is getting the same nutes as the other 3 plants in the garden and they aren't doing this.
I've never seen this before so I'm not sure what I'm looking at?

What is this brown intrusion upon my plant? And how do I obliterate it?Another question?! Anyway, what the hell is this browning? I think it's light burn. But why is it lower too? PH? Magnesium? Nitrogen toxicity? Par: 1300 PPFD
