Day 16. Growth has been good, did experience some leaf tip burn and discoloration, I think it’s cal mag deficiency. I added cal mag to the regimen and also hit it with a cal mag foiler feed right before the light turn out.
Rapid start has the root zone going crazy, I’m highly impressed with the current results.
I plan to start LST sometime this week.
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!
