I was making reckless mistake for exposing the plant into too much light causing burnt tips during seedling stage going through day 5. Light intensity was at 75% with the height of 28 inches.Any recommend on recovering these baby ASAP ?

Crispy dry margins on the upper leaves. Please see detailed pics through week 5 of flowering. Pics from different days are available.
The younger plant was showing what I thought to be P and K deficiencies on the leaves. Growth stopped too. Increased its nutrient amount 3 days ago (bloom-grow-acti). Since then I observed some bud growth but the problem on the upper leaves continue. Any ideas?

Nutrient problem??? Excess or deficiency?
What do you think is the leaf issue? Open to second opinions. Most everything stayed the same, except: > increased water: 2L to 3L per 7 gal of soil > introduced a bloom booster > increased volume of worm castings, molasses, mycrobes and ethylene to the tea

Top set of new growth part is a little crispy and curling taco style. Is this down to heat ? Growing in greenhouse in U.K. other plants are okay and I do have a second plant in the same pot that’s perfectly okay ?

Help diagnose hydroponic plants! Too much light/heat? Nutrient issue?
The plant's leaves on the right are wilting and drying out, while the leaves on the left are spiking. Just did a nutrient/water change but it didn't help, and it looks like growth is being stunted on the right plant. Humidity has been around 45-55 rh and temp 70-80F
