Heavy burn, usually either too strong mix or insanely low pH. Your grow heavily compromised, unless its coco, then flush flush flush with correct ph ASAP !

Over-fertilized and that's crazy.. just give adjusted pH water 3-4 times and she'll be fine again.. maybe a little flushing helps too, 20% drain and then rebuild... good luck!

Hello all, I am having some issues with my outdoor grow. It seems the leaves are beginning to turn yellow. It has not received nutrients I’d say in about a month. The main reason for asking is because I do not want to over correct by adding nutrients if that may not be an issue.

Should I be worried with yellow and brown tipped leaves? Will it affect quality or yield? Can I correct this? With my nutes I used sturdy stalk and Ph’d water 6.3 and I feel it could be the lights but it also started from over feeding Nutes. B4RNS called it!

Do I have a deficiency problem or am I ok? 3 lower leaves on both plants started with the tips browning but now the leaves are going yellow. None of the newer growth has been affected but the 3 leaves seem to be getting worse. See pics in week 4!

Nitrogen deficiency or could it be nothing In the pictures you see some yellowing and small spots. I don't know if it's Nitrogen deficiency or not because it stays with those two leafs.

Yellowing on lower leaves. Any idea what this is?Don't think they should be deficient in anything yet, they're in new Ocean Forest soil and only on day 11 of veg, no way they used up what's in the soil yet. More details in my grow diary comment.

Yellow tips New grow, new leaf colours! I think it could be over feeding, but would like to see peeps opinions if possible. Have stuck to the feeding schedule, but the fabric pots might be making things more complicated somehow?
