started grow question 4 years ago
I seem to be experiencing nutrient burn and nitrogen toxicity, is this fixed by just flushing with PH’d water for the next couple feedings?

Possible deficiency/humidity/pH problem
I've been struggling with same problem from beginning of grow - leaves having these dry yellow/white spots. The first week I used too high pH which later I replaced by rainwater - new leaves were healthy, but last night I left tent at 70% RH. Somehow it returned - still rainwater

All of my plants have started to burn yellow in colour when they switched to flower, they have also lost they lovely green colour and started to go lime. Too much nitrogren still in the soil? Or Just a deficiency? They have recently been fed 1ML fishmix and 2ML Bloom.

Does anyone knows if should I flush the pot ahead of time to reduce nutrients levels?
As you can see from last pic from week 6, I have used pre amended soil with 2.5 % of Nitrogen on dry mass. (sorry for the italian). Should I flush the pot ahead of time in order to reduce nutrients level so to both solve the yellow tips problem and favour the flowering stage?

low pH problems
I discovered that I had irrigated with water at pH 3.5 for at least 5 days. yesterday I used water at pH 5.7 and today I think it will increase to 6, but I noticed that burns are already starting to appear so should I continue like this and hope for the best or do a root wash?

Nitrogen toxicity??
Does this look like nitrogen toxicity to you guys? I have fed them only a little fish mix but I added some humus (worm castings) to soil when they got re potted and maybe too much? There’s no claw but the plant is dark green and tips are starting to go. I have flushed any ideas??

Repot today or wait?
Planned to repot into a 20L pot today, so I did a test unpotting to check the roots etc, heard some minor root tear and put it back in its little pot immediately - within 1 hour I noticed signs of transplant shock. Ordered recharge. Should I wait to transplant?

Leaves change during 5th week
You can see during this week that the early leaves are falling down, and some leaves are showing some kind of burn. I thought it was due to overwatering or not so good soil draining. Any tip?

Light or nutrient burn?
Ive been having yellow tips on the tops of both my plants for some time now, I already raised the light up a bit higher than the maximum height the manufacturer recommends, but Im still having the yellow tops. Could this be nutrient instead of light burn?

Is this heat light burn? HPS 600w at 20cm
Is this light heat burn?? These are all buds at the top of the canopy and they are the ones nearer to the lights. I have 2x600w HPS, one with a cooltube and the other just with the wing. The possibly burnt buds are the ones under the wing (just 20 cm).
