i think i should reclarify myself... i meant lockout... but theres that much nutrients in jiffy seedling starter mix? that is all the core of my pot is....i was pretty much following tangs sched except i fed them on day 7 instead of day 10... i will stop the sensi grow... since there was not problems before i fed them should i be ok to keep giving them AN's Piranha(micro),taruntula(micro),voodoo juice and carboload(feed for micro's)?It's way to early for any defiecency to show up so rule that out.You should have enough nutrients in the soil for at least 3 to four weeks so over feeding might have that effect.It;s not bad enough to worry about so just give it plain ph'd water for awhile and see if the new growth is still effected.
i try and make sure there is no resting water on the leaves as much as possible...Any way it burns from water droplets and light? Or nute water burn?
i think im going to do as you and @namvet25 suggests and just not feed them the sensi bloom A&B as they were doing fine before i added that.hmm very interesting.. I know I have gotten these spots in the past and it was my mistake with water droplets accidentally splashing on leaves. Wish I had an answer for you. This early I would not change anything unless those spots progress. Obviously they may get bigger as the leaves grow... Just watch the new growth.
Do you have other seedlings in the same mix right now or just this one lady? Are the others okay? Nevermind just read your first post again. 2 of 4 affected.
PH? although this young shouldn't really matter either!?
Could be nute burn but IDK... lol
Sorry I know I am not much help. If it was me... I would just keep at it and not make changes yet. Hopefully somebody with more knowledge can address this or fingers crossed its a fluke(Sending good vibes your way).
Trip-- nice job on dealing with the acidic soil! Fuxfarms has been awful about this these days, many complaints, few good bags,... your initial pH was typical! As Nammy said, it's too soon for any defc. to start, and pH is fine, so no lockout happening,... that starter soil is basically barren though, by design, so until her roots make good progress into the outer soil blend, a little food is okay, like 20% strength... how much did you dilute? Symptoms are so minor, they don't look like anything specific at this point,... did those few appear after you fed? ... spots happen sometimes, often something more physical in nature, but an ever so slight nute burn may cause such spots too,... watch for worsening symtpoms, but new leaves look fine, so likely you're all good!....
