Foxfarm first grow

I believe it’s a phosphorus problem i been using ffof soil and the trio brand i watered yesterday with 6ml of tiger bloom and 9 ml of organic big bloom the water went in with a ppm of about 550 and the runoff was 1330 i use two 1200w aglex lights one in bloom and one in veg temp is about 75 humidity 50% should I add more tiger bloom to the next watering?

Hey there...Looks to me like too much nutes. That soil already has nutes in it, right? Which at this point, in early flower, a lot of is used up, but not all. They are very green!!


I would skip the nutes all together for a few feeding and give them only water with calmag and some additional Epsom salt at about 1/2 teaspoon per gallon for a week or 2...and then I'd probably fertilize at 50% or so when they need it, if they need it. But that's just me

Welcome to RIU

Could I use Distilled water, Cal-Mag and PH Up?

I would give them the extra magnesium found in epsom salts...It's very economical and it will make your plants thrive....and you probably won't need any PH up. ...My ph falls minto range with ro water, cal-mag, and epsom and that's all I feed, until the final weeks of flower when they need a little boost, but I'm using organic super soil.
