So I am growing 3 strains of autoflower right now. Northern lights, grape are and royal critical. All in 7 liter fabric pots with pro.ox hp. Running ph perfect part a and b grow and bloom mixes ran the recommended dose of 1-3 ml per liter for first 4 weeks. Plants grew great started noticing yellowing in first week of flower on new growth slowly progressed to purple edges and dying leaves on top growth. Purple started to develop in week 8 or 9. All plants have same symptoms just some progressed earlier than others depending on time in flower. Later the flower worse it got. I did start reading ppm in week 6 after noticing the problem and it was very high 2200ppm. I have flushed multiple times to get down to 800ppm now but maybe too late? This isn't bud rot is it?

nutrient deficiencies

raise your lights as your leaves are not able to photosynthesis properly

So I lowered intensity to under 600 ppfd should I go less?

Waiting for the amber tricomes seems like it's not progressing anymore

If you have been giving nutrients it's probably lockout due to PH being off. Do you know the ph?

I haven't given notes for weeks because I had nutrient tox in the beginning with a ppm of 2300. I brought that down to around 1200 now ph was high at first and that has come down to 6.5 now
