Phos def?

It does have that look.

When I see a sign of a deficiency the first thing I do is determine "does my feed have enough of that element?" If it does then there is another cause for the uptake issue like pH or nutrient antagonism.

What is your feed mix?

My feed mix is 4tbsp big bloom, 15ml tiger bloom, 5ml calmag per 1 gallon, only reason I'm dubious of phos def is because if the tiger bloom being an npk of 2-8-4 I ph water to 6.3-6.5 also

Ok, for starters, too much P and look very much like too little P.

The feed mix you describe would appear to be really strong on the P. I don't have label percentages for the Big Bloom or I could run the #'s, any chance you can take a photo of the label percentages for that product?

4 tbsp is alot of big bloom.

Alot of big bloom

As you can see here the reccomended values are 6 tsp for the 1st 3 weeks and then thats cut to 3 tsp.

15 mil is 1/3rd more than the reccomended values of tiger bloom

Should be introduced at 25% of those values.

That schedule is full strength which should not be being used tbh.

there is nothing for numbers in big bloom , its just soil food. the numbers are well under .5 on all 3 macros. thats the only one of the line up you can use full dose an never hurt anything. 15ml of tiger bloom is a full dose. (max in my opinion) i would rule out P def with that much TB but im not 100% on that with your strain.

Big bloom is 0-5-5

Tiger bloom is 2-8-4

Having a hard time finding the label #'s for the Big Bloom but I did find these #'s FWIW and plugged them into my calc.

So running it through my calc your feed is something like this (I used botanicare cal Mag Plus)

Indeed pretty strong on the P, of course I don't trust those #'s as I don't have the actual label to work off of.

Depends on your water I suppose. What is your water source / PPM?

You can add magnesium with epsom salt and not get more calcium. I might consider adding a little more cal mag to up the Calcium if it's RO water, then perhaps a little epsom to give the Mag a little more boost. Could be that there is calcium in your tap water so if using tap you may only need a little epsom, hard to say without knowing about the water.

Thats RO water and should be very near 0 PPM. In the case of RO water I always start out with full strength calmag. I use calimagic (it has less nitrogen) and with RO I go right to 5 mL per gallon. This replaces minerals stripped via filtration. Using RO water is great because you know whats in it, nothing. So you can add exactly what you need without guessing whats already there (ca and mg are commonly in tap water at some level). So your mix should include calmag at full strength.

If you see any signs of a mag def, first verify that the pH is not too low, that will severely restrict mag uptake. If calcium is not deficient then using epsom salt would be recommended.

For reference, one gram of epsom salt per gallon will provide an elemental PPM of 26 Mag and 34 Ca.
