hey there Cudeech, looks like you have a pest infestation. these little buggers are tiny though, check your underleaf to see if there are microscopic black dots there. if so, i have bad news. but the good news is you can add bacilus thuriengiensis to get rid of them. Hope this helps ! 🚀

Interveinal chlorosis and dead spots on leaves, deficiency?This started appearing about a week ago, after I watered until runoff with plain water. It's on a couple of leaves higher up both plants and seems to be progressing. I am feeding advanced nutrients Grow Micro and Bloom but have been using very low doses, like 1ml/L.Leaves.

What to do? Where am I at now actually? I’m lost and slightly discouragedWhen should I add happy frog fruit and bloom? This is my 3rd grow and im 0-2! I have a overfeeding problem but I’ve learned to be corrective and precise with ph and ppm and be pest preventative as well (heavy handed waterer as well..im trying). It’s day 5 of flower and I’m lostLeaves. Veins - yellow between

Is this nute burn / deficiency? Or light burn? Or both?What's going on with the intervenial chlorosis? Is it nute burn (zinc + manganese + iron potentially)? Is my proposed solution of only going with pH-balanced water a good mitigation strategy? Should I just not add super soil out of the gate?Week 2
