HELP! Tips turning yellow/brown

[MrMotion]

It's only on one plant out of three, on the first node of one of the plants, the plants just got trimmed (manifold) about 36 hours ago. The other 2 look just fine. My grow journal is posted as well.

Only think I can think, is my pH has been around 6.5 the last week or so,, which is in the high side i know, but I thought acceptable. Ill lower it closer to 5.5 next time I mix water.

Coco
600w HPS
GH nutes

Thoughts?

I want to catch it early

Yellowing of the bottom leaves is usually a sign of a hungry plant but since you just manifolded it I’d go ahead and remove that lower growth before increasing nutes.

They are fan leaves associated with the newer growth tips on the manifold, still remove them?

Nope I’d leave it then until defoliation before flowering. If you’re in coco get the ph down some. Manifold is hard on a plant and if everything isn’t in check they’ll barely grow for a while but it’s my favorite technique. The final result is by far the coolest looking
