Please help! My big plant is dying!

[db2]

• Please Help! This is a Dinafem Critical + plant which has been vegged for about 2 months under t5s in FFoF soil. I always keep the ph of my water at 6.8-7.0 It has been flowering under a 600w hps for a few weeks now. About a week ago I started noticing brown spots all over some leaves and reddish blotches on leaves normally towards the tips. The leaves affected started from older growth to newer. I really need some 2nd opinions about what is going on before I jump to conclusions. I dont want to force anything and make things worse.

Magnesium is what I'd look at. Epsom salt if you agree.

I use tap water for watering. I thought magnesium was already present in tap. I may be wrong. What makes you think it is a magnesium deficiency?

The spotting from the tips in.

Hey man
Looks like your growing in soil???
Do you use water straight from the tap?
How often have you flushed?

Use calmag not epsom salt. the yellow leafs are normal that late into flower. if the spots bother you get some calmag plus and start using it on a regular basis it only takes half a teaspoon per gallon.

Is calmag+ safe to use with tap water? I thought it was for RO or distilled water. I have Botanicare CalMag+ on hand? Can too much of this cause any lockouts or deficiencies?

Calmag can be used in any grow setup,yes you can have an abundance just like with anything else.
