Hey buddy the Ph should go down to 5.5 - 5.8 at Hydro. This may fix your problem. I find the Ec value a little high with such a small plant :-) but only my opinion :-). Do they give Cal / Mag extra? when Yes, how much ?

Hello.. Hope you are well.. T h if ur other plants aren't affected and they have all had exactly same conditions then it is either.. Just a genetic flaw in her.. Or, she has slightly different needs than ur other strains e.g..less/more watering/feeding.. Different ph ranges.. If u did her again and changed these parameters she wud most likely react differently.. Its alot of trail and error tbf.. Stay safe n gud luck on future gardens.. 👍🍀

Is she looking healthy? Day 4 after being planted. I apologise for the frequent questions but as this is my only seed I’m very paranoid. Haven’t been able to use the sun much as it’s been hiding behind those pesky clouds 😞 so LEDs mostly.

I keep seeing this reddish or bronzish discoloration in the new growth when it’s just starting. Almost a purplish color at times. What kind of deficiency could this be? Or something else entirely?

Leaf colour and buds Are the leaves still too dark and should I be flushing more? Just worried I've ruined the growth with the overfeeding of nutes now 😓. It seems small but I guess there's still few more weeks to go? Also for nest time am I supposed to remove the lower smaller buds? Thanks 🌈

What nutrient is causing this?I know for a fact that it is some kind of nutrient issue. I’m not sure what but that’s what makes the most sense. Because it ONLY shows on very early growth and then disappears as the new leaves continue to grow. I’ve been through very cold weather and never seen this.

Outdoor aphid removal suggestions?Looks like I may have aphids on this plant. Small holes nibbled through, spotted one tiny critter and knocked it off, and then sprayed 1/4 spirit vinegar + 3/4 water mixture on the underside of the leaves, hoping to be rid of the pests. Any further suggestions or thoughts? 😐
