I am about 5 weeks into the flower cycle of Girl Scout Cookies and Cactus Cooler and plan to harvest in approximately 2 weeks. I’ve been adding Fox Farm Big Bloom, Fox Farm Grow Big, Fox Farm Tiger Bloom and General Hydroponics CaliMagic to each watering about every 3 days. PH has been adjusted to 6.4 and soil is good at 6.8. Using LED Spider Farmer G5000 light at 90% dimmer setting. The brown spots started on the Cactus Cooler but the leaves on the bud are worrying me. Is this simply a case of too much nutrients? Ant help appreciated

Yes too many different nutrients. You will loose all those damaged leaves. Classic case of over feeding.Smoke Ganja create Peace Respect Nature don't trash the Planet

Agree with budgal on this one. When I used their trio I used it at half strength and every other watering in soil. So I basically fed them once a week with just water in-between. Plus in flower your supposed to skip the Grow Big every other week. Still had a small amount of nute burn.Last edited by Bowhunterwoody; 08-02-2026, 11:40 AM.

Agree with Budgal and Bowhunter. May I offer a simple nute trick I use?
I use half strength GH Trio in 50/50 coco/ perlite, pH'd to 6.0 - 6.1. I VERY carefully monitor the leaf tips for the browning indicating nute burn. When, if, I see this on one of my 10 - 12 plants, I immediately use only water for a couple of days then restart nutes at an even lower dose. Have never had a problem like your pictures.
