It would help if you could take pics in normal lighting. Pics under grow lights are disiving. Looks like over fertalzation to me . When plants are young they need vary little help especially in fox farm soil .

I would hold back fertilizer till the 2nd or 3rd week of veg fox farm ocean forest soil is sufficant fertilizer wise for 4 weeks of growth in my expeirance. then it tends to taper off . In small potters plants tend to get root bound before they require any additional fertalazion.

If you want to use liquid fertilizer you may want to cut the ffof soil with a less nutrient dens soil option.

With the added perilite you are lowering your soils ability to hold fertilizer. Check out slownickels thread discussing cec.

Good luck hope it helped .

6tsp. is a lot of Grow Big. Give them straight water, pHd to 6.5. I wouldn’t start nutes back for atleast a week or more. And when you do start them back, only give them 2tsp. As long as the plants stay green, keep the nutes low. If they look light green, bump them up...slowly. Maybe 1 to 2 tsp. at a time.

Just like Vanilla Phoenix said, back off the grow big.

Ocean Forest has about 5 weeks of base nutrient built in. you're likely pretty locked out after stacking food onto food.

6 tsp/gal of grow big is 600 ppms, that every other watering would be about 600 ppms per week. Seems like too much.

Can u test ur runoff?
