Trying to identify deficiency

When I zoom in on the leaves I see lots of white specks on some of them. That can be insects so try checking under the leaves with a loupe or magnifying glass.

At one point I sprayed all my plants with “Super Thrive Foliar Spary RTU” after letting it dry, I let my plants go back under my lights. The plant with the most intense light got sever spotting and burning from the dried residue on the plants. The rest of my plants got minor spotting like you saw from zooming in.
other than treating a minor fungus Nat problem early in veg, I haven’t seen any other insects.

It’s hit or miss when growers keep blending coco with FFOF. Next time let the FFOF do the bulk of feeding. Amend with perlite or pumice to aid in aeration and drainage. When you combine 2 different medium together ( especially when each has its own PH requirements) it muddies up the grow.

With fox farm Ocean forest, would you only use cal/mag w distilled water? At what point would you want to add nutrients?

so should I not follow the fox farm schedule?

thank you for the help.
I HAVE NOT started flowering yet.
therefor, I have only used big bloom and grow big along with the other products recommend along side them. Big bloom was only added in my last feeding, after symptoms started showing
How would I know when the right time to start adding phosphorus?

I've been using AN nutes for 20 years and have never followed their schedule, I follow my plant's schedules and they have taught me lots.

With the 3-part nutes I start them with a 1-1-1 ratio. Equal amounts of each and just half strength, (2ml/L), once growing well every 2nd watering tho lately I've been using half the feed at each watering which seems better for the plants. Once they have begun vigorous veg growth I switch to feeding in a 3-2-1 ratio, (G-M-B). This limits the amount of P and K they get and won't use that much of while vegging where N is needed more. A week before flipping I'll give them a good feed of 1-1-1 and a half dose of Big Bud to 'prime the pump' so to say. The stretch period is a huge growth spurt where ALL the nutrients in higher doses can be put to use if everything else like light is also maximized. Stretch is the only time I add CO2 to help them bush out as much as possible. Right after the stretch I switch to a 0-1-2 ratio aka Lucas style feeding. Waiting 3 weeks or until the stretch is over before adding any bloom boosters is way too late IMO.

I don't know all the ratios in the nutes you are using but the AN ones are;

Grow 1-0-4, Mg, aminos and fulvic acid.

Micro 2-0-0 Mg, Ca, B, Fe and Mn

Bloom 1-3-4 S, Fulvic acid, Aminos and Wet Betty, (a surfactant)

Big Bud is 0-15-35, 20 aminos, 10%S ascorbic acid ,(vit. C) and citric acid.

Any old CalMag with iron will do. Currently using REMO. I don't buy any other AN stuff other than Rhino Skin for silica to use in DWC mostly.

I'm growing in soilless ProMix HP when in pots or DWC and feed the same kind of way in both. Never have to check pH with RO water which is great. With the pots I add myco, crab/lobster shell, bio char, insect frass and sometimes some manures and EWC for added flavour. I'll also water in some of my unfiltered dugout/tap water to get a good dose of healthy bacteria and other goodies that are sure to be there.

I never had any luck growing in dirt so kind of worked out a compromise.








I also supplement by grinding up some of my own supplements. Vit. C, Fe, selenium, B-1, Zn, citric acid and of course Epsom Salts. A good dose in early veg then again when flipping. Not sure it does much but can't hurt I figure.
