First grow, deficiency help!

[Rubia360]

Hi I am a first time grower. I have 2 gorilla glue plants (not auto flower) vegetating on week 7 in a grow tent with 2000 w LED. Right now theyre on 12/12 lighting
Schedule, using Fox Farm soil and feeding them with the Fox Farm trio nutrients. I came across some deficiencies looking like white ash and do not know how to cure or what the problem is. I would like to know how to treat please

and any suggestions on how to make my fan leafs bigger as I’m afraid they’re not big enough to hold buds during flowering stage.

Hi Rubia360
Welcome.
I have only been growing for a year, but I will try to help.
Have you checked for tiny bugs with a microscope?

looks like a bug problem.You looked close at the leaves and under them with a scope?

you can’t make fan leaves bigger, it’s up to genetics and then grower skill to keep them healthy green tho. The fans don’t hold the buds but fans are solar food collectors, used for nutrient storage and transpiration etc, the fans do help buds to grow by providing these services mentioned.

light colored spots look like thrip spittle or honeydew never had thrips so let’s see what collective says about it

thank you! I went out and checked with a scope and it does match the thrips spittle like the ones shown on google. I’m going to get a spray for it.

Ok cool just be careful with oil based sprays and strong lights - leaf burn is a real thing. It’s best to spray before lights on and to raise your lights or move the plant out and allow foliage to dry. Thrips hang out under foliage so elevate plant, mix well, shake often and spray leaf undersides first
