Light burn, Heat burn, bugs and/or overwatering? Need help

DO NOT FEED THEM MORE!!!!!! They are being burned by too many nutrients in your soil now!! I've been looking through your diary and the questions you've posed about this grow... and I have to ask - what kind of soil are you growing in? I noticed in the last week that you reported a 900 TDS and this seems VERY high given the fact that you're not giving any nutes - the TDS should be reading down around 250 for this age plant! ... so the soil has to be the source and it would seem it's much too hot for these ladies... but this is only a guess! But these plants are being burned alive... I like to grow in ProMixHP - it gives NOTHING in terms of nutes but has mycorrhizae in it for the roots and lots of perlite for aeration... I like to be in control of what nutes my plants get and when they get them... If these are photos (I can't really tell from the name or the seedbank), then I would suggest trying to transplant them into a neutral medium such as the ProMix... if they're autoflowers, even though they absolutely HATE being transplanted, I would try to do the same except doing it extraordinarily carefully so as to not disturb the roots at all.... Good luck... p.s... btw, I do not see any issue with bugs as I did before... so I apologize for that (I wouldn't return the Spinosad... keep it for potential future use!)...

Dang, even after a good ole fashioned flush and cutting back a lot on nutes, they're still burning. I agree with GG, your soil must really be loaded with nutrients. Just water with pH'ed water. Don't give them any more nutes and pluck off the leaves that are really burned up. If they keep getting worse after that, transplant them out of that soil into some different stuff. I'm not sure what premixes are good because I mix my own, but I think GG recommended some? Anyway. I see a floppy plant! Give her some inert soil mixed with peat moss to help stabilize her so she isn't flopping around. I really hope this cycle turns around for you, growmie. You'll figure these problems out, I have faith. Good luck!

Im growing in biobizz light mix I have only fed them once with half dosage (**9 days ago, before the problem took this big turn) with rootjuice. Since then, only 6.3 ph water My EC is 0.9+- (0.1)

Hi there Oh they really dont look to good, your diary says you haven’t fed them yet? There at a vital stage of root and heigh development so need to be fed they will drain and nutrients out the soil in no time, Id defo give them a good veg feed and quick hope they bounce back 👍 Best of luck 🌱

To clarify, they are photoperiods :) Im growing in Biobizz LightMix I only fed one time ( 2/9 with half of the dosage recommeded ) so i they cant be overfed. Always test Ph before and after nutrients, aiming for 6.3 but happy with anything 6.2-6.4. I am doing my best to get temp down, and to compensate for the stress they have been going through, i have turned down the output of my light by 25% (Lowers the temp as well) I got two fans in the tent. One oscillation fan at the top (not point towards plants but the walls to get the airflow down) And a station fan on low speed, moving the Co2 and airflow upwards. Previous solution: That HAS not been working. I will keep the light on 25% until they recover Give them ph balanced water atleast 2 feeds. Keep temp down a steady Stay on point with the VPD (0.6 -0.8 kPa) https://www.dimluxlighting.com/knowledge/blog/vapor-pressure-deficit-the-ultimate-guide-to-vpd/ Co2 In the tent. Temp 26-29 Degrees RH64-70RH Ph Level 6.2-6.4
