Fixing Nutrient Burn with Coco in High Frequency Fertigation
kansasscott725started grow question 6y ago
High Frequency Fertigation in Coco, nutrient burn issue. I know I have to be careful w/ diluting substrate. Do I also need to always include some type of Cal Mag in my water, even if just topping off reservoir.
Dial back nutes or increase fertigation frequency? H&G pic in gal

Hey there Kansas, I gotta admit I don’t know why you’re asking about this stuff seeing as how picture perfect everything is right now for you. If you’re worries about the burnt tips , you might as well dial back the NPK just a touch , but if you don’t the plant will muscle through it as it grows anyway. Same with the cal mag, yes you always need it , but you’re already adding it. So don’t stop. The fertigation frequency is less important following the wet dry cycle correctly . And you’re doing totally fine. Hope this helps ! 🚀

An alternative is to increase plant capacity to process fertilizer. Humic acid is a good additive without interfering with current regimeb.

Defoliation late in flower on Auto'sI like to defoilate, If I were to pick majority of the fan leaves off of these plants being Auto's, will they react or stress too much? I like to defoil near the end of flower to really push all the focus to the budsites. Happy Growing!3y ago

Crispy bottom leaves (tip)Need help!! Tip of bottom leaves are kinda drying out (crispy dry) and are a little bit curled down.
Not sure if it’s improper ph, too much nutes or overwatering.
Top leaves are fine, I dunno where I was lacking. Help a brother out, what do you guys think?

Possible deficiency/humidity/pH problemI've been struggling with same problem from beginning of grow - leaves having these dry yellow/white spots. The first week I used too high pH which later I replaced by rainwater - new leaves were healthy, but last night I left tent at 70% RH. Somehow it returned - still rainwater
