My guess would be youve got some salt build up going causing some toxicities and locking out some others causing deficiencies. It appears that you have some N Tox going on judging by the dark green and glossy leaves, that can lock out calcium which it appears to have a deficiency of also. Id flush real well, maybe with a salt clearing product like floraKleen, then give just pH'd water or very light feeds the first couple waterings afterwards. Good Luck!

They are in a peat moss compost, i have been adding in 0.8/1ml/l into feedings of vitalink calmag. Just flushed with 6.0 ph water to clear anything in soil and added in a light feeding after with some calmag and bloom nutes to see if this will help her out

Indoor LEDs grows usually need some light calmag in the feedings. What are you growing in? Soil requires less then say coco. 🌱

Popped up around last week (week 4, monday). Prior to week 4, i had been watering with tap water, which in my area is pretty hard.(7.8+ pH) Been correcting pH to 6.8 with each watering since. (2 waterings since then.) Should i just continue feeding 6.8 pH water or add cal-mag?

Please see the 2 photos marked in the diary. Is this a classic PK burn? Did a feed with no MegaCrop, no cal-mag, just PK boost at diluted dosage. The coppering and yellowing has come sudden. Leaves are crispy where burnt. I hear its easy to burn with PK boost. Did I do that?

In the 3rd photo in week 12 there is spotting on the leaves. Does anyone have an idea of what that is from? A deficiency? I had trouble getting the nutrients right and that showed up first after I flushed for a few days.

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?

LEAFS DYING The edges of the leaves are dry and black. Every single point of the leaf is burnt(black) or yellow...even some edges on the leafs of the coal are burnt. I guess it’s overfert...but I just flushed. Is it Ph? I haven’t checked in awhile. Is it they ready to be cut down?

Seeing some top bud leaf discoloration Starting to see small dark/black discolorations on the leaves. Since I don't know the genetics, I can't tell if it's prone to dark leaves. Could it be signs of anything else? Note: Started watering only using TopMax and ActiVera because of some possible Nitrogen toxicity
