These three girls are all wilting and/or barely growing. I'd say over-watering except I've only been giving maybe a quart then waiting till the soil dries a little bit. Not too much tho. Could it be a nutrient problem already?

What’s your opinion on this one?
What you think about it? Is she getting too much? I’m not giving her too much in my opinion. Her stems are purple and the leaves are yellowing a bit. Watering always with ph 6,3-6,5. Thanks for your help! Happy growing!

Nute burn or pH Flux
Ive noticed the tips are the faintest of yellow. Maybe ive mistaken Nute Burn for pH Fluctuations? Diagnosing: pHing both tank and run off showed different ranges. My CYCO Coco pre-mix was ph buffered. The De-Gnat agent that goes over the coco for mite protection maybe causing.

Nutrient Correction?
04/21 - Noticing some possible nutrient issues with the Fruity Pebbles for several days now. She has much more of a pale green color than the others. I’m thinking maybe just a super small amount of Amino Acids with a little Epsom Salt? Maybe fulvic acid and some calcium?

High TDS and low ph runoff - Lockout? deficiency?
Struggling with some bad soil (beginners mistake). I water with dechlorinated tap water at around ph 7.4 and 400ppm (not feeding yet). But runoff ph is 6 and around 1000 ppm. Am I dealing with a N-lockout? why such a ph difference and high TDS value?

Rusty Leaves
3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera. I also have slight "clawing" on many of the upper leaves. Mg/Ca lockout because of nitrogen toxicity possible? Doesn´t seem to be fungi, as there are no spores to rub off.

45 days flowering yellowing
45 days of flowering, is it a bad yellowing or it's normal for this phase? Always did 1ml/L of biogrow, I think I'll put 2ml/L till flush. It's nitrogen, right?
