3rd week since 12/12 and chlorosis is getting worse !!! Will my crop be crappy ?
Brought EC to 1.6, added 21ml of calmag, had to add 2L of osmosis water because the EC was 1.78. I changed the bad Ph probe and I let it fluctuate between 5.75 and 6. Should I remove the aluminium foil on the pot to let them breathe ? Not sure they are overwatered, I'm desperate

N issues
This girl suffered from N deficiency very early. So I gave it nutes. Nutes gave it N toxicity. So I flushed the soil with ph’ed water. You guessed it, it’s lacking N now. The problem is the pot is still very yet and heavy so I don’t know if I should water with nutrients

Nutrient problems I cant identify confidently as I am a noob
Hmmm, I've got some nutrient issues by the looks. Is that dark splotch on the leaf indicating phosphorus deficiency? My pH is OK. Looks like a few things are going wrong. Thanks!!

Are these droopy lower leaves a problem? Only with one plant
Hello Beautiful People! Two days ago I noticed in the morning that one of my Raphael plants had droopy lower leaves. I watered it with some herculean harvest and after night time it bounced back. Today it is droopy again. Is this a problem? How can I fix this? Thanks a ton !!!

Blue Dream Auto from fastbuds, 16 day's old. Leaves look dark green, I'm thinking it's from too much nitrogen or it's sensitive to nitrogen because I haven't fed any nutes yet. Ffof ffhf mix half and half with perlite added. Should I do a mini flush in a couple weeks? Advice plzz

Deficiency or screw up?
What is this? At first I thought it was a phosphorus deficiency so I flushed with extra bloom nutes & overnight the damage doubled. Is it a pest or did I just fuck up bad? She also has seemed to have stopped growing. No noticeable diff in size recently

Liquid oxygen
Would you all use this in your water when trying to give oxygen to the roots? I’m noticing some really dense, not drying up that quickly soil so it’s making me think that they can’t breath. I don’t know, just making sure every part of the plant is happy & healthy.
