Multiple issues same conditions

Hi all. I'm looking for some advice on just what array of issues I'm looking at with this veg cycle. The plants are various strains some from seed others from clones. They are all in the same media which I've just started using pro mix with mycorrhizae and biostimulant. Using fabric 5g pots. Feeding botanicare soil pro line at 6-650 ppm at 6.2. They are setup in a 4x8x6.5 tent. The lighting systems are a little strange but temporary as im adding a third flowering tent so there's some shuffling. In one half there's a CULTIVAIRE™- LED HORTICULTURAL LIGHT a 368w light that's perfectly shaped for one side of the tent. The other side started with some over kill lightning in a iluminar il8 with height factored in. After an older flowering light became available i swapped it with a hlg-550 with a dimmable dial. Heat holds pretty stable between 72 -78. Ive added a co2 bag to help offset the heat stress. The feeding schedule is nutrients/water/ nutrients/nutrients/water . I am considering applying a foliar spray using karma and cal mag with silica. Any thoughts would be greatly appreciated truly

Calcium and magnesium deficiency. You can foliar spray Epsom salts for the magnesium. 1 tablespoon per gallon of water.

How high is this light show above the plants?

All these symptoms are a result of cal mag deficiencies? I use cal mag from botanicare at full strength every watering. Should i increase to 1.5x the recommended rate? Also i don't have epson salts can I foliar feed with the cal mag? At full strength? Thanks again for your help

The lights are : cultaviar is 6" the hlg-550 is 18".

Your pH is way outta whack. I would guess too high. Your medium is a peat based medium which causes pH to raise over time. Also, your medium is designed for hydro nutes. Keep your pH 5.8-5.9

You are giving them soil based nutes. This combo is possible but takes much more nuance and understanding. I would switch to a basic hydro line, leech them for a week with a base only nute combo for 3-4 days at around 6-700ppm, and then slowly up the feedings to max 1000. Less is more, give them 50% feedings once a week or so. This should get you on the right track. Fuck all the amendments, just use some good base nutes and a good enzyme if you're gonna spend money on something.

So I have a emerald harvest box kit from a convention handout and ive been wanting to try mega crop for a while now. Would you recommend one of these as a replacement for the botanicare pro soil line?
