recovery from early gnat damage

i got gnats at week 2 from seed and it took about 2-3 weeks to get rid of them. they made the plant show signs of its root damage and i pulled the worst one. i got rid of the gnats but now at the end of week 6 from seed im showing signs of disease or deficiency

Has anyone who got gnat root damage early on keep the plants and had success or will they usually keep growing but never pull back? Should i add anything? they are in roots soil with orgonismXl and the Buddha veg by roots has been used once at half strength. water about every 4 days sometimes 5 since getting the gnats. they have been in 5gal smart pots for the last week

lights are MH-hps&LED combo thats the odd color

i also went pretty heavy on mosquito dunks(one crushed disk per pot) but i dont think they caused it

Get yourself a moisture meter,it's a great tool to prevent over watering.Your buds will most likely end up with a lot less resin

that sounds horrible.
so damage in veg does weaken flowers? i may just start over since i havnt went 12/12 yet
anyone know if its a huge difference ? i could maybe flower these in a make shift secondary room with my led

Burnt edges, next time wait longer before adding nutes to rich soil. The burning caused the issues not the gnats. Gnats have to very bad and est in the rootball before they affect the health of the plant.

the plants started looking worse than this before i added nutes. the gnats hurt them when they were just getting the 3 fingers and still babies.

ill accept that its just nute burn, i hope it is.
the roots are growing and are white not that tan ugly color i transplanted last week and the roots had took over 1.5 gal but the gnats hit them hard at 2 weeks old

i figure i got the gnats in the roots soil and 12 days old was too small to put in the 1.5 gal pots and it stayed wet too long and they got a stronghold

if its nute burn the orgonsimXL isnt good i guess
