Not enough info. Are you soil or hydro? Temps, feed rates, what nutrients?

This is a case where a picture is NOT worth 1000 words

I grow in Hempys also. What nutes and what ph are you feeding at?. What is your feeding frequency? Your second photo looks like Potassium (K) def. What is your runoff ph and ec?

 

[Growzlow]

Ph at 5.8. Gh trio and calmag
Feed feed water going about 4 days and buckets are light.

Hydro systems should never get plain water except when flushing at the end. What is your EC/PPM of your feeds?

What RockinRobot said is dead on. In a pure perlite Hempy you should be feeding every other day like clockwork. Once the roots have made it to the bottom of the pot you could safely feed every day. Like RockinRobot asked: What is your EC/PPM of your feed?
