Aluminum sulfate or sulfur will lower soil.. if you think you took out most nutes then feed at half what you were and watch new growth.. Cheers friend

Hello friend,
No need to worry. It's great that you found the problem so early on. Id say water with nutrients but definitely ph a bit lower than you normally would...if you usually do the 6.4, try pulling down to 6-6.2 then check the runoff right then...but also check it in another day or two and see if there's been much change.👍

Critical Purple: Leaves slightly yellow.Just started my first grow. I1 placed the light high in the tent and the leaves slightly turned yellow. I lowered it yesterday to 18” over the top on the plants. Just wondering if I am on the right track to solve the issue. The plants are still growing. Minimal nutrients 1ml/gal.

Yellow/Brown/Spotted/Crispy Lower LeavesWhat is wrong here? Gave an extra dose of nutes but the problem only seems to be getting worse and spreading up the plant. Definitely effecting the bottom leaves more. Others said to just increase N-P-K ration, but this seems like something specific.

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flowerThe odd thing is that only some leaves in the middle of the plant are affected. My thoughts were Nitrogen or Manganese deficiency or maybe light burn (why in the mid of the plant tho?)? I feed Biobizz Bloom, Grow and TopMax, no Problems until now.

Is the slight yellowing ad curling of these leaves ok or indicative of something?Curling and yellowing of leaves in a few instances, both near the top and bottom of the plant, with no noticeable discoloration on the branches in between.
I'm feeding it 1/4 strength Grow Big (2Cups) and 1/4 strength CalMag (1Cup) when I water every 3rd day. Ph runoff 6.8.

I’ve been feeding them both the same I’ve missed the shoter one of the soil is still damp. I’m guessing nutrient over load so thinking do a flush3y ago
