Hello All, I'm currently in my 4th week of vegging. Two of my plants seem to be giving me problems. I made a few newbie mistakes, but as far as I'm concerned I fixed them all . I've attached pictures below!

I'm using a 6 bulb 2ft t5 ho for the vegging ,6 cool bulbs. Water every other day with nutes off and on like recommended. I'm sticking to schedule with that. Also supplying c02 and a cool mist humidifier, fans, etc. my temperature is about 80-85 on average with 40-45 humidity. Recently sprayed with bug spray to get rid of a couple mites. No problems since, except the yellowing /grey spots on the leaves!! On a 18-6 light schedule, lights are a couple inches ahead , without much heat so I don't think that is the case. Pleaseeee comment with any suggestions / ideas on how to fix this

Thank you so much that chart helps
Alot! Im starting to think phosphorus or potassium. I also think it might just be shock though from me finally adjusting my ph. Some
Of the leaves were dying off so I trimmed the infected ones off , essentially starting the growth over new. Two of mine are growing absolutely beautiful so they must just be the stronger ones, as the other deformed ones seem so far behind. They are all being fed the same, same lighting, etc

It's the bug spray making you think you have deficiencies. If they aren't formulated specifically for plants (even the home and garden types) they will start trying to kill the plants because the leaves can't breath through it. If you sprayed the soil with "raid or HotShot" then you need to rinse the soil by flushing. Seen it many times when buddies spray their plants with raid to kill off fungus gnats, aphids or thirps. Just going to have to baby them through the stress. Can't say if they will live as it seems to be hit or miss after bieng sprayed with bug spray... good luck, but don't try to treat the symptoms, you will just make them worse. No more over the counter bug sprays for cannabis, get some stuff from Sierra Natural Science. They have free samples and they won't hurt the plants.
