Very interesting thread , even though it's a little old I'm going to get stuck in lol
I'm new to coCo & hydro nuts so I found this thread interesting to say the least , I've been using GHE 3part with a few other things like ' mycos granules sprinkled on the roots, veg booster from growth technology 'the same company that makes the IONIC line ' and I'm mixing a ratio of 2.5ml per gal of micra/grow/bloom for a EC of 1.0 and I've noticed tip burn but also pale green leaves?
My plants are 4weeks from seed today and for the most part look good' but why is this happening? I'm reading I these posts people say "I can't run LOWER EC than 1.2 or 1.4 ? I'm struggling to get them over 0.9 with the ph being at a steady 5.8 in and 5.9 to 6.0 out watering in 6l pots every day.
My background EC is 0.5 so no Epsom needed and all environment conditions are perfect ' any ideas about my ratios??
Lights out sleep time..
Would be better off giving my girls a flush and then re-think my feeding ratio's? Maybe try the lucas 8ml/16ml at half strength until I flower??
Any advice would be amazing
