This is technically my first grow, but more like a 2.0 version. this is my do over, these plants are clones taken from my first run that we kept in case we went wrong with the first. happy we did it as the initial too were stunted from nitrogen toxicity and one gave airy popcorn buds and all the other started to do the same but hermied. These clones just started week 2 of flower Saturday but I believe I see signs of deficiency but the run off is quite high. Do I ignore runoff and pay more attention to the plants? Or its possible my ppm meter is trash. Plants are Gelato 33, on day 129, in soil w pearlite no amendments, a trellis was added as they started getting to tall for the 5x10 and to close to the light. The run off will measure for 5130, 1278,1986 and it will remain in this range. I’m thinking a flush is necessary but think it will push the defiance more. They were last fed 3ml cal mag, 2micro, 1.5 grow and 1.5 ml bloom of gen hydroponics 2 weeks ago, and I’ve been watch the run off since. Any guidance/ advice would be appreciated. Happy growing 😃

To be safe id flush with ph'd water at about 6.8-6.9, then end with feeding whatever your nutrient schedule says for the week your in and probably ph that at 6.7.
Some pics look like magnesium deficiency, some pics look like zinc deficiency and some look like over watering. If you are in soil the ph definitely has to go up. I don't know the schedule of your nutrients but the amounts you said seem small for the age. If you think your ppm meter is off there is solution to recalibrate. If you could get a ppm reading your confident with it would help, most likely will be high with the low ph of the medium slowing the uptake.
What’s your runoff PH?
