ok something is very wrong.

can you please tell us what your soil is and anything you have added?

What water do you use?

what Nutes do you use?

what lights and how long?

how old are the plants?

tempratures?

PH of the soil?





Do you have any very small bugs on the leaves or soil that you can see...a magnifying glass may be needed. (they look like they might be bugs in your pic)


Do you have a humidity tester?

yes i do see little tiny bugs

temps and PH are ok, PH isnt great, but it will survive near 7, mine are always 7.

your flouros..what frequency are they? ie 2700k or 6500k or like grolux dual specrum?

someone with more know than me eeds to pipe up, but all that MG stuff looks like a massive overdose, however if they have survived in those same pots of soil since the begining the soil nutes may hopefully be dpeleted...

i reccomend a flush. check the faqs for flush solutions =)

not sure what that is (internet on a go slow)..i would consider trying to identify it and by a predator, such as lady bugs for aphids e.t.c
