Excess calcium ?
AS420started grow question 3 years ago
Hi, the young top leaves are starting to have a yellow tip, I guess this is a potassium deficiency due to an excess of calcium in my watering water that is hard and I add extra calgreen and the fact that I water with fertilizer 2/3.
Could you confirm the problem ?

If you've got hard water AND you're adding extra nutes, I would think your thinking is correct... the question is why did you feel the need to add it? Your grow looks wonderful so far, I'd stop fiddling around with adding extra anything unless you're trying to solve a problem... There are some excellent foliar sprays on the market (FOOP being one - and no, I have no stake in that company! LOL!) if you feel the need to punch things up a bit but I'd get back to the normal NPK feedings if this was my grow. You really don't have anything to worry about!
Good luck!

IMHO it is your light is too close to plant. My Goldleaf did same. I backed off light a half inch and it seems to stopped.

Instead of adding a specific nutrient which could do harm if we misdiagnose or overdose, maybe amend a little bit of general compose (GAIA Green 444) into the top soil to supplement overall micro nutrient is a nice soft boost.

Yes a potassium issue and looks like you need more magnesium. Hope that helps.

She still seems pale-ish to me. Been feeding what I think is enough nutrients, I may be wrong. New growth always seems kinda nitrogen abundant cuz they very green but seem to keep fading as newer higher leafs grow. Should I flush or add more nutrient? Starting week3 flower

Grower questionAny ideas what the issue could be?
Few weeks into flower. Dealing with fungus gnats and have kept the population very low.
Temps do get high, at most 95 (hot I know). I cranked down the lights to their lowest setting (100 true watts LED).
I have adequate air flow.

Plantule aux feuilles vert clair. Engrais organique et fibre de coco.La plantule s'est bien développée, mais ses petites feuilles sont encore pâles. J'ai utilisé la dose recommandée, puis légèrement augmentée au second arrosage, sans amélioration. Dois-je ajouter plus d'azote ou passer au stade suivant de nutrition ? J'utilise l'engrais organique.
