Yellow leaf tips that become brittle.
OoOgAuTostarted grow question 2 years ago
Leaf tips are starting to become yellow & brittle & they flake off on touch after a couple of days. Started a week ago. Turned the lights down to 30%. Introduced cal/mag + silica. Hit them twice before the lights turned off with a foilar feed of cal/mag.
What’s wrong? TIA

…And cotinuing my prev post. As you’re growing in DWC - the roots may show some symptoms too.
Make a new res patch give about 200-250ppm of CalMag for the base then get your EC somewhere between 0.7-1.2 / 350-600ppm.

Foliar symptoms appear as K (Potassium) deficiency.
You’re having way too high EC and therefore the excess salts creates nutrient lockouts. Plants may express the symptoms as a deficiency or excess symptoms on the foliage.

It is a nutrient overload problem, not a lighting issue.
You are feeding them too many things.
They certainly don't need bud candy or terpinator at this stage - they are baby plants, baby plants need baby feeding!

An EC of 2.2 seems high to me, The base nutrient chart says for 2ml/l since your adding everything else in as well you might need to dial back a bit.

always grow with cal mag , especially in hydro. The good news is , you're already doing all the right things, the damaged leafs wont magically recover but the problem should have stopped or should stop within a day or so of spreading . Just look out tomorrow to see if it's at least slowing down, if that's the case, you caught it , which is a good thing. Hope this helps ! 🚀

Yellowing on older fan leafHey guys, my photo sour d has some earlier growth showing some yellowing in the center of a few leaves. I fed this plant a foliar spray of cal mag plus way back in the 2nd or 3rd week and it got burned on the leaves but does this look more like a deficiency?

Am I overthinking things?Any idea what’s going on with these ladies? Or am I just over thinking. They just seem a little unhappy. Watered 750mil yesterday morning the last time before that was 500mil Saturday night. Could they be a little overwatered?

Late flower issues- chop early?Week 8 of flower (haven't been best at keeping up with diary). Poor girl is deteriorating rapidly but I don't know why. Too late to fix, but too early for ideal harvest. Should I just let her ride or chop early and try to salvage what I can?

Yellow leaf tips in flowerShe's pretty far into flower, in DWC, and the environment and nutrient schedule have stayed consistent for a while now. I'm using GH Flora Trio at 5ml of Micro, 2.5ml of Gro, and 7.5ml of Bloom per gallon.
The leaf tips are looking burnt, should I ease off on nutrients or what?
