are my plants hungry???probs start of week 6 flower

Hi i have 7 plants in 30l pots 3 in scrog the other 4 arnt.have them under 2 600w hps soil had slow realese nutes im it so o was real light on the feeding.but have flushed and gave a feed still no change if not getting worse. The 1 in scrog has spots every where and leaves drying up the 4 that arnt in scrog seem to be having completly diff issues.any ideas?i have never had probs like this before

.

The darker leafs with all the spots and brown patches is of the scrog plant the faded leaves are of other 4

Precharged slow release soil can cause a host of issues I’ve seen it many times.

Different strains? Have you grown these before ? 3gal pots? How long was veg?

I would give those light colored girls something to eat And check my pH

Nope all cloned of the same plant which i done last time with no probs and great results. Started seeing a couple small brown patches on leaves near the end tho.so maybe the are just hungry.yea im pixkn the soil is what giving me the problems ive never had so many problems lol.and they are in 30l pots.ive been giving em feed water feed water for last 5 or 6 days so will know in a another week if they were hungry or not sort of looks like the fan leaves on the 4 not in scrog are trying to go back to green i would of veged for a good 7 8 weeks if not more.so i was thinking the stuff in the soil should be used up by now
