In need of help (pics included)

Most of the issues look like is near the middle on the plant . Like the fan leaves halfway up the plant. So it seems like it's a calcium deficiency ?

that doesn't look like cal. it looks more like manganese, possibly mag, but really looks more like mang to me

How often are you feeding??? And are you ph ing the first run off out of the pots when you water and also the ppm in your water??? IMO I think it's being over fed what I'd do is flush a couple a gal of water through her then when she dries up hit her with a good light feed but that's my opinion. Like Roger said it could be mang. But it's hard to tell without a list of foods you feed and how often you do so I hope this helps.

Tomato fertilizer I used was 2-7-4. and I only fed that to them one time, about 3 weeks ago at half strength.
Since then I've been giving them superlative,
And that I've only been given at 1 drop per 4 ounces of water.

your in veg and your 2-7-4 NPK ratio is not giving your plants enough nitrogen and giving them too much phosphorus

I only gave them that tomato fertilizer one time. I have flushed with RO water since then. I sprinkled a little bit of garden lime in the soil and I have been giving it a little bit of superthrive every third watering

superthrive is okay but fine line between okay for ladies and killing them..use superthrive cautiously and from my experience when i have used it, one or two drops is plenty for a gallon of water, if you have been using RO water to water you might have to get some cal-mag to supplement.

***edit*** for myself I don't actually use superthrive during the veg/flower cycles...I have used it when i took cuttings and soaked them in containers that contained superthrive, to me if used right it increases the amounts of roots that form, but could just be my imagination

I bought a pH meter. My water is 8.0ph
Is this the cause of all my problems? I also bought a bottle each of ph up and ph down as well.
