Hey Derfans!

to help you we need more info.... is that coco & hydroton pellets? how often do you water? are you adjusting ph? if so to what value? how often do you feed? do you use cal-mag? what nutes are you using? whats your temp & rh? what kind of floor is under the tent?

i see a few spots on the leaves..... do you have a jewelers loupe? have you snipped a few leaves to check for pests or eggs? most critters you won’t see without serious magnification

lastly what’s up with the black tubing - is that water or are you pumping air to air stones?

I’m going to shout out to @Bill284

some of that leaf taco looks like heat stress but you’ve got some twisting & spotting going on there too. also strongly suspect you are not feeding or watering properly.... but hit us with answers to the above & we will do our best to get you sorted!

Hey @013 thanks for the call up. First off you can't set your pots on a concrete floor. Your nutrients need air in mix cool temps can't hold oxygen properly therefore depriving them of proper nutrition.
Do you have a calmag supplement. Mandatory in coco.
Your room temp 24 is good. What light are you using and how far away.
Lastly 1.2 ec seems a touch high in veg but not terrible. I might cut that strength back a touch till she is healthy again.

Unless your tap water is full of calcium id use it every feed..
That mh bulb is what 90 cm or 3' away and I think it might be adding to your taco issue. When she goes into flower she is going to stretch right into the light and cause problems.

90 cm should be enough if you have good air flow and temps. A little calmag will help her. Keep posting pics if she doesn't get better let me know.

Okay I will do thanks for the help do I add cal mag to water before Nutes ?

Sorry yes put calmag in first , it helps with uptake of other nutrients.
